@@Nitrousatoll I hope things ended (relatively) well for you lol. I nearly learned the hard way several times... I am very lucky I've still got my car and my mates.
Also, since no one mentioned it, watching a lot of car crash compilations on youtube and memorizing what conditions lead to most crashes makes you very aware to those look for those conditions when driving
These cam videos are sad. Always half a story. The guy bleating on about someone under taking? Has been blocking the lane on a personal crusade for some sad reason 🤣 Most are cut short, especially on fb
DanDanTheFiremans motorcycles crash review compilations are one of the best hazard perception materials I’ve seen on TH-cam, very much agreed, watch crash compilations so you know what to look out for
Not even on a Sunday at 5am - there could be someone from the opposite way that also decided to go on a spirited drive. Just never drive beyond your sight/vision. It's risky.
It's actually funny because a minute before he said that, there was a pheasant running across the street. Now guess when wild animals are the most active.
Definitely, I would say I'm more comfortable and experienced than your average driver as I've been doing track days for years, racing etc... but even that can't prepare you for someone deciding to follow racing lines on a public road around a bend/corner or attempt to overtake at a bend that is essentially a blind spot. Unless I can see there's absolutely no one else on the road or nearby for a decent amount of distance, I'm not pushing into those 3 digit speed limits. That would be absolutely selfish of me.
As a youth in early 80s, I found that out 🤣. Milk man 🤣🤣🤣🤣 I didn’t hit but it woke me up and I will never forget. I learned 👍 I regularly drive above 100mph but have never had an accident. Due to reading the road and not being an idiot. Slowing as I pass traffic. Before you judge? You don’t know if I can legally drive like that or not in uk?
I actually had to do basically this exact braking practice before getting my drivers license, in Sweden everyone has to do a driving exam where you slide cars around and get "reality checks" like what's shown in this video. It was a real eye opener when the instructor made us do a "moose test" at a high rate of speed but with a twist, the twist was that the cones were set up to have a route on both the left and right side of the "moose". The instructor would tell us which way to turn over the radio about 1 second before we had to turn but every single driver including me told the instructor that they told this information to us too late (in our minds, it felt like we had already hit the "moose" when he told us which way to steer). We then went slower and he did the same thing, this time every team managed to avoid the hazard. Reaction times are a real issue we all have to consider
There's a cognitive difference between audibly being told which way to go, and visually seeing which way to go. The true Moose Test is done when driving toward a barrier and a cardboard cutout appears on one side of it as you approach. It's easier to respond correctly with the visual stimuli.
moral of the story is that public roads are not for racing, go to the track, as much as you try to control all the things you can , there will always be things beyond your control, even if its 1% risk/chance, that 1% can cost your life or someone else's
True, you can stop quickly on tiny drums if your tires are good enough. Applicable force to the pads is rarely the limiting factor except in large heavy goods vehicles, and some old worn out bicycle brakes. Otherwise you could say "I can stop faster because my leg is stronger" - an argument I've never heard for braking performance. The big discs are for accelerating and braking over and over again, where drums or smaller discs would overheat. It's also possible that from speeds of over 150 mph, you can overheat stock brakes in one fell swoop. With more power utilized and downhill, you can put more kinetic energy into the car and take it out again, over and over. On the public road I'm more of a hypermiler, so drums all around would be okay for me. They don't rub as much and save fuel anyway.
@@MickDrivesCars Except they don't. Smaller brakes on an economy car will stop the car equally as fast as your sporty big ones. All what brakes do is lock up your wheels, from then on the braking performance is all dependant on your tyres and road contact, and external factors like road condition and weight of your car etc. It doesn't matter if they are big or small brakes, as long as they are sufficiently strong to provide the pressure needed to lock the wheels, which all modern brakes do, big or small. The advantage bigger brakes give you, is that they don't fade as fast or overheat when you perform aggressive braking multiple times in a row. In an economy car, you'll (hopefully or you're driving poorly) only need aggresive fast braking in an emergency, so not often. Think about it, if bigger brakes actually would make you stop significantly faster, all cars would be equipped with it, as basic road safety is paramount in the industry and not something that would be exclusive to sport cars (just like airbags, ABS, ESP, etc.). An economy 'normal' car drives just as fast on the road as a sport car, and needs to slow down just as fast as a sports car. Only difference is it doesn't accelerate that fast and doesn't need to do aggressive manoevres over and over again.
In germany we learn a handy formula in driving school. Your emergency braking distance (brakes fully applied) can be roughly calculated with: (Speed(kph) / 10)². So at 60mph (100kph) your emergency braking would roughly take up 100 meters. And at 30mph (~50kph) it would be 25 meters. Depending on the size of your brakes, this formula might or might not work for you, but for almost all stock brakes this is a good one to know. Drive safe everyone!
@@dammitdadSpace is a vacuum. In the UK it seems that people only think of the space in front of them as stopping distance and forget space behind them, cutting in front of other cars inches from them.
double the speed is usually 4x the distance as braking distance is proportional to the square of the speed. i wish this was something we actually learned in driving lessons and just overall physics of driving like weight transfer
the most i ever learned was how to correct a skid and even then it was useless info for anything not RWD. they told you to lift off and counter steer which in a FWD car might not actually save you. Though I don't know if this is true if say, you hit ice, but at least in my sim racing, the best way to correct a FWD sliding is to put some power down to get traction off the front wheels. I once had to correct a slide in my AWD car which was the same procedure as RWD, but it was also low-speed. Wish I had some dirt roads to practise skid control in, or snow... maybe next winter.
@@MidnightGreen4649 yea i think skid control should be mandatory as well as full stop from high speed with and without abs. better yet get ppl to learn in long rwd cars and experience body roll and understeer and oversteer
@@nicktodorov669 Maybe we'd also get more young people interested in cars too. I made a sudden left with one of my friends in the backseat and once the shock wore off she thought it was kinda fun.
They do in Germany. This kind of stuff is part of the theoretical exam as well as some rules of thumb to estimate stopping distances at different speeds. One thing also thought is that there is a reaction distance (much longer than the simulated moving foot from gas to brake) because humans don’t react instantly. Additionally on narrow roads you should see twice your stopping time because oncoming traffic needs to be able to stop too.
For that brake test, I recommend doing it down a hill. I tested my brakes for breaking distance, and the one time I needed to stop in an emergency, I crashed because it was downhill and the car did not stop in time. I even had video of it, and my reaction time was not the issue. Definitely tested brakes down a hill.
Fun fact bmw has a system when u take ur foot fast of the gas it shorts the distance on the brakepads so the when u hit it it instantly stops. Also on rain it shortens the distance so there is less water in the pads
this is very much true.. driving in highway is like 70mph braking on that speed seems normal from inside the car but its a fast fast speed. so breaking is must to know if you wanna speed. very good video! kudos to u mate
Once, in a parking lot, I tried to brake from 40 mph to 0 as hard as I could. I stopped hard enough to make me feel quite light headed. Ever since then, the only time I'm tensed up when braking is when I'm in bad traffic and a car's behind me haha.
Great video! I always say this It’s about your mindset and attitude when driving and how much control you have. Your driving literally tells the type of person you are not your car. Also when someone is in your car, you are responsible for that person
As always, great video, but I have a few fun facts to point out. Sunday morning has less traffic, but probably more drunk drivers going back from parties, so I wouldn’t say there’s no chance of someone driving on the wrong side :) Driving at night has a benefit of seeing someone’s high beams around the corner, so you actually have wallhack. Your brakes are only as good as your tires. You could have Superman holding the rotors, but with no grip it’s just gonna trigger ABS anyway.
The less traffic there is the more likely there's wildlife around or that you'll be the first person to come across things like downed trees,big rocks or a washed out bridge. Unlikely but I have seen them all. I was a passenger when we hit a deer at night. It jumped out and did the classic deer in the headlights look. Luckily we were in a Yank Tank and could drive home. One day in Colorado we saw deer after deer crossing so I let the car behind me pass. Sure enough one jumped out between us but it was daylight and I saw it in time. I've seen many branches in the road and one tree,many rocks and one boulder. The scariest was being the first one to find a bridge washed out in the fog at night. There'd been heavy rains and something just didn't feel right so I slowed down to a crawl. There's bold drivers and old drivers but very few old bold drivers.
5 AM on Sunday actually can be even more dangerous btw. It's safe but can be another racer enjoying free roads ahead :D 2) can be a village tractor broken and without lights right around the corner or horses 3) drunk people heading home after a long night. But you know what I mean because the video is cool and you're telling the right things
Especially that part on doing a track day,it really helps you know your car well It's strengths and weaknesses.Because you will always be alert about what's going to happen rather than getting a nasty surprise.
In algeria we say: drive as if everyone around u is a bad driver, and any pedestrian is blind. this makes u account for any possibility anywhere anytime. You cannot imagine the number of times this mentality saved me. especially that drivers here are crazier and the laws are broken much much more than where you are.
10:00 Remember that you should be looking for potholes, too, in addition to incoming traffic or tractors. When you go over a small hill, you can see that there are no other cars but when do you actually see the road surface well enough to be sure that there are no potholes? If you don't want to break your car, you have to be able to stop before a huge pothole in the ground, too. You cannot assume that there's free lane to go around it.
@@MickDrivesCars The "double the speed 4x the distance" is something you do in physics class to learn about how kinetic energy works. the formula is (1/2)m(v^2), where v is the speed of your car in this case. if you replace that with 2v (so in this case you double the speed) you have (2v^2) which is 4v. since you come to a complete stop, the brakes have to dissipate all that kinetic energy, so at twice the speed the brakes need to remove 4x the energy in every case. Also, tires play a huge role as stickier tires can prevent brake lockup and the activation of ABS. I only had ABS come on when I was braking hard and turning in the rain doing autocross. So either my tires were great or I was not fast enough :0
Great video mate! It baffles me the amount of people who drive right up the back of other cars pushing their cars to the limit around every corner regardless of the conditions or capabilities of drivers around them and somehow get away with it.
I did a safety driving course. One important tip about stopping distance is to count the seconds. Always be at least 2 seconds behind the car in front or any conceivable obstacle (find a marker by the road that matches the car in front and count one elephant two elephant). 2 seconds seems like no time, but a LOT can happen (and go wrong) in that time. Make it 3 seconds if you’re stressed or visibility is bad or it’s raining.
Cinetic energy goes up as a quadratic function (E = (mv^2)/2) so it makes sense that it was something like 4 times the distance: E1 = m*v^2/2 E2 = m* (2v)^2/2 E2 = m*4v^2/2 = 4E1
That’s because the resistant work done by the brakes is Fxd where F is the braking force (assumed constant) and d is the braking distance. This resistance work must dissipate the entirety of the kinetic energy 1/2mv^2. Therefore: d = 1/2 mv^2 / F Hence the quadratic dependence of d on v. You can also derive this from the equations of movement.
My driving instructor was very adamant about visibility, speed, road design and stopping distance. He’s a fanatic too. Wanted me to use more power of the car :) Taught me how to drive safely, and instructed me when I can let loose and use a little more juice (but not over the speedlimit. He’s an instructor after all). This stuck with me and has kept me from getting into accidents. And it’s exactly the type of stuff you’re teaching here :)
Tons of people driving fast don't realize that they also have to be prepared to stop and turn even faster. They never teach you these things in driving school, so most people are led to think going above the speed limit is dangerous, and the car, rather than the driver, is blamed when inevitably, people panic, freeze, and hit something hard and fast. I'm genuinely convinced that beyond airbags, ABS, TCS, and ESC, car safety systems are kind of useless. Ah, and crumple zones and whatnot are also nice to have too, up until it means your beloved car is totaled. I always have a personal rule which is to drive in a manner which makes my passengers feel safe. Inevitably I wind up putting them to sleep lmao.
I'm a car guy, owned a dozen cars over time. Occasionally people recommend me cars because of their crash safety features. I'm like - wouldn't you rather avoid crashing in the first place? Most people treat electronic driver aids as the foundation of their driving skill.
@@JayMaverick There IS a benefit- lower insurance! I am lucky that my car's driving nannies don't interfere with the fun much, and so I don't really bother turning them off except for the stupid lane keep assist. If it's found that you disabled any safety system then insurance will probably screw you over. sadly that's the nature of the game. My parents were concerned about the crash safety of my WRX (which is really funny because they got it new for me as a high school gift) because it was a sedan... the thing is so stable through corners it scares me, and the brakes for a car built from the parts bin are great on the street. Feels much safer than any other car I've been in, save for my friend's dad's Tesla. And that thing feels safe just because he's a very experienced driver.
@@MidnightGreen4649Exactly, I don't get the discourse around safety features being "intrusive." You really mean to tell me that automatic emergency braking, cross traffic warning, pedestrian detection, so on and so forth are actually intrusive in your day-to-day driving? And is it really that hard to use your damn turn signals to stop the lane keep assist from kicking in? I don't personally have these features, but I feel much safer on the road knowing that the 5500lb Ford Expedition behind me won't kill me in a rear end collision if the driver is busy yelling at her kids in the back seat.
@@d47000 You must not have read my initial comment then. In MY car I have not noticed them intrude on my driving. I would rather do without them, as the mere knowledge of these safety systems' existence affects your behavior and attitude towards driving the car itself. In my opinion that change makes for more distracted drivers who assume the car will compensate for their abilities. In my car specifically, I do not drive in a manner where the systems activate and I consciously feel it. So as far as I am concerned it does not matter to me whether they are on or off. In the end, and I say this as an engineering student, the optimization of one quality will inevitably impede on other qualities. In just about every practical case... that's not good at all in product design. As far as lane keep goes... there's times when you do need to cut the line slightly and it would be silly to give your turn signal. For example, road work. Some systems also do impede driving in cars because they are predictive, and it's hard to accurately predict 100% of the time when a crash will occur... so you have models built into the software that tries to account for that 99% and sometimes you do get a 1% false positive, or even worse, a 1% false negative. If the safety system is never active then you are probably a good conscientious driver. But Karen arguing with her demon spawn will find a way to rear-end you even with her car being designed to not crash into anything.
I didn't catch it in the vid, so I wanted to emphasize how important to distinguish the difference in braking distance when you have really grippy tires vs hard tires. From the factory, your brakes are designed to apply more than enough force for any emergency stopping situation at least a few times consecutively before overheating. Entertaining and high quality content as always thx for the upload! ^.^
Even at 5am on a Sunday morning always drive within your viewable stopping distances....never drive in such a way that risks others. The overall message in this video is extremely useful....and I wish a visit to a test track were part of obtaining a driving licence where stopping distances and real car control could be experienced.
Its wild that not once was it ever mentioned about the car behind you here in the US where theres a lot more traffic the chances of being rear ended is way higher than in these roads with no cars
EK=½mv² Increase in velocity has a massive change in the kinetic energy. I realise this is a very basic way of looking at it but it gets the point across
Me too, but reality and sim racing are two completely different things, and I would be extremely careful about over confidence driving, because you’re a good sim racer.
The Sunday 5 am example goes both ways, there might solve some Saturday night out dude thinking the same under the influence of alcohol, I saw a study most accidents happen during early mornings of Sunday, it’s best to have a visualization of how much you can control instead of relying on low traffic.
Practice...practice...practice... Experience is your best ally just like most things. Knowing your car is paramount so you understand your limit vs car limit and finally, most importantly, understand anything can happen and when it does, there's no magic trick. The faster you go, the bigger the consequences. Whether you are responsible or not, more speed = more damage. Let that sink in and you'll naturally allow yourself wider margins when having a little fun, not just because you have a good understanding of where you're at but also because you have no idea where everyone else is at. Experience just helps you anticipate/react better and read other people's state of awareness and/or mindfulness. When you come around a corner, all bets are off. It doesn't take much speed at all to generate lethal force with a fat heap of metal. I love driving. Always have, always will. Posted speed limits are not my religion. However, I try to remain very mindful of all the above factors and it keeps me on a fairly tight leash, naturally. It doesn't matter what you're driving. The unspoken rules apply.
Conversely, experience can also be our worst enemy. Where I am from, experience tends to lull people into complacency, especially if drivers see other drivers successfully cutting into lanes (& successfully brake in time to avoid accidents). Most of the time, it is only when one has been in an accident or been in a close call that one realises how easy it can be to get into an accident.
@@matthewlee7405 For sure. I am however specifically preaching experience in mindfulness which goes a long way to making up for all the npc's out there and more generally minimizing risks that go hand in hand with the operation of a motor vehicle.
one thing that causes a lot of highspeed crashes is when your in a difficult situation and you take to long, precisely, (less than a second) to decide what cut or what your going to do to get by upcoming traffic. I see a lot of guys hesitating a lot on there decisions when theyre swimming or cutting through traffic and that's an easy way to crash.
“People say I shouldn’t drive so fast on this road since there are driveways and someone could back out and hit me, and they’re right (but imma do it anyway 😏)” me too man me too, I can tell you and I have the same passion for driving, I think just like you do, keep up the videos, love em!
When I was younger in my teens I was more reckless but in my mid 20s, I personally just don't have that much trust in other road users. Someone can decide to overtake at a bend or think they're following a racing line and use the opposite lanes, I only really hit those extremely high speeds if the roads are absolutely clear and I can clearly see there's no vehicle around. If it's a long straight and no opposite traffic then I'll absolutely put my foot down but if there are a lot of bends where visibility isn't 100%, it's not that I don't trust my own abilities because I do but I don't trust others to not do something stupid.
Golden rule: You must always be able to stop safely on your side of the road in the distance that you can see to be clear. In situations where you share the road with oncoming traffic this should be half the distance. Brow of a hill, limit point on a bend, heavy rain or fog, vehicle in front, darkness... those are all the distance you can see to be clear.
Magazine 60mph-0 distances (usually 30-35m for production cars) and 70mph-0 distances (usually 45-50m for production cars) are good indicators. You will need a heck of a distance to slow down from 120mph which you will hit on some stretches of straights on b-roads. Also, you don't always need to brake to 0, if you spot something out of your current calculation (seeing some light, objects on road, some car coming out from a side road etc), you can always slow down to a comfortable speed and speculate. Always see far and look at the direction you want to go. There are also lift off/snap oversteers for newer drivers, changes in road cambers, changes in elevations especially during bends, bends that get tighter, these kind of things can really throw you off when you are speeding. Rain/puddles/sand/wet leaves/snow/ice/oil slicks will amplify all situations. So yes, always start slow, then speed up, real life driving is not a video game where you can rewind or repair everything with game credit.
5:22 The car will not stop a lot quicker, it's brakes won't fade as fast, almost all brakes on consumer vehicles are capable of locking up the wheels (unless they weren't serviced) and ABS will kick in before that to keep it at peak deceleration. the most important variables on your stopping distance are traction and the ratio of vehicle weight to the contact patch of the tires
Nice demos, I will try to get my young son to watch the channel and to also subscribe. My driver friend and me have almost come to serious grief when driving down a gravel mountain road, when his wheels locked up, instead of counter steering, he tried turning with the slide, and we ended up perched halfway off a 300-metre drop. Cheers.
Even if you have enough distance to stop at your visual limit, the other car also needs that same distance, so you would need double the distance. Just slow down and I also think you need to try the anti-lock brake and see if it is better at stopping.
Yes Tires! I know this is probably not a major issue for you but for me where I am having tries that are good in the winter or in mud are essential... don't cheap out, buy decent tires😊
6:30. Double the speed, 4x the distance is correct. The brake's job is to dissipate kinetic energy (speed) as heat. When you are going double the speed, you have four times the kinetic energy since kinetic energy is 1/2mv².
One point that wasn't mentioned is that if somebody is overtaking and coming towards you, you have to at least half the distance, so the other person can stop too. This is especially important on smaller roads.
It’s funny to notice that the volume knob is on the passenger's side, unlike in left-hand versions of the car. As a driver, I have volume control on the steering wheel, but my passengers have to reach over to the driver's side, which is quite inconvenient
Mashing the brake to 100% and triggering ABS definitely contributed to the 4x braking distance. But yeah, active critical thinking is the key. I genuinely don’t understand how someone can send it with their brain relaxed…
It's funny, I made a video a long time ago about braking and how you should progressively load the front suspension to get maximum brake efficiency. People told me I'm an idiot and just mashing 100% and letting ABS take care of it is faster :) I made a conscious decision in this video to not do it ''properly'' but rather brake as someone might in an emergency. I recon sub 25m is possible if I got the tires/brakes warm and did it right.
@@MickDrivesCars Well, seems you’ve outgrown those people lol. Threshold braking is King. Good choice for the video, though, as not everyone will have experience with braking to just before your ABS kicks in/will want to practice and familiarise themselves with it.
@@MickDrivesCars You did it right. I heavily doubt one would be able to do a proper threshold braking in emergency conditions, its just too much stress. May be after a sec of ABS braking confident driver would find enough courage to lift the brake pedal a bit, donno =). 1st normal reaction would be emergency braking and thats ok I believe.
Great video for youngsters. In the 80s in my XR3 van, twin carbs& fast road cam btw; I was having fun at 5:00AM. Roads must be empty…….bar bloody milkmen 🤣. Close, but ok. At 100mph +to 156mph, I’ll speed on an empty stretch. As soon as I am overtaking, I slow to a stop/avoid speed as the traffic I am passing could do anything. Maybe something worth filming? Clear again, foot down. (Run flats on AMG Estate btw before someone says blow out) yes I have had blowouts on other vehicles and motorcycles. Front on a bike is fkn hairy. Stayed upright. Another thing, tailgating is bad. You are better cautiously undertaking than tailgating someone that refuses to move over when there’s no reason to be in that lane. Ice throws another wild card. Be aware if you are climbing a mountain in winter for black ice. Only time I have crashed a bike. I was also taught how to drive on ice including skid control. If in doubt and you loose control, so long as impact isn’t imminent, just take your feet off and steer. No abs, eba etc then. Also lectures off cops which is now sadly lost to £££££ I learned by those lectures. Since 1984 passing my tests, I have never had a serious accident. Ice was something where I lived. A beautiful twisting road ascending more than you think with a stream at the side. Where I crashed was where it crossed. Mist had created black ice across a hairpin double bend. Lovely dry cold day otherwise. In the summer on a bike, you can ride 70-100mph (I was younger then and roads were a lot quieter) You could drive on a Sunday morning, 20-30 miles and not see another vehicle then. Driving was enjoyable then. Speed doesn’t kill, driver error and speed in incorrect places does.
One time I was driving on a highway behind a truck and got to a part of the road that's totally straight for a while, allowing great visibility to pass. There were some cars coming, so I waited then, the opposite road completely clear I switched lanes only for the truck to shift over too as turns out there was a bicyclists riding on the side. They were completely covered by the truck so there was no way for me to see or expect it. Luckily there was enough shoulder for me to halfway drift off and I also sped up to quickly pass as I was right by the truck as that point. So even when doing everything you can there can still be curveballs. Now I keep in mind how much shoulder there is as well when I pass in case I need it.

Oh my God there is so much common sense in this. Drive safe!
Kinetic energy is equal to 1/2 • mass • velocity squared so double the velocity is exactly 4x the kinetic energy the brakes have to dissipate, so yeah double the velocity is 4x the braking distance (assuming energy dissipation is the limiting factor and not traction etc) 😊
Kinetic Energy KE = 1/2 MV^2 So when the velocity increases your KE is going exponentially higer with V^2 So if you double your speed your stopping distance quadruples since your breaking power remains constant for your car regardless of your speed.
Great video, Mick! Definitely a must-watch for beginner drivers. It's sad that on the driving lessons (at least here in my country), they don't mention 90% of the stuff you've said in this video. I really love the content you do
Also, with manual, ofc we usually go in the highest gear, however, if you get to have the ability u can use ur gearbox to emergency brakes, be careful dont blow ur gearbox going into a too low gear
5:11 Stopping distance does not depend on size of your brakes/brake pads and only depends on your tyres (grip) as long as your brakes can lock the wheels. Larger brakes are only useful when you brake a lot in a short period of time as they are harder to overheat.
Bro wtf happened when you counted meters "2...4...6...8..." HAHAHAHA WHAT 😭😭 Amazing vid man, can help a lot of people who are starting out for sure!! Be safe everyone, but don't forget to be fast when conditions are good 😝
6:23 It has something to do with how kinetic energy is "created," since the formula (Ek = 0.5mv^2) has v^2, exponentially increasing energy with a linear increase in speed.
11:00 Remember that people pulling to the road are expecting other road users to follow traffic rules. If you brake the law, be prepared to be the one that is responsible for every action on the road. And think about the possible consequences before taking those extra risks.
As a fellow BMW driver, I approve of this message. My driving may at times seem erratic to others but I am fully in control and have calculated the location, direction, and state of the vehicle now, and 10 seconds into the future.
These are the most essential skills to stay safe when driving fast. Even for normal driving they're helpful (yes, it's rare but sometimes the speed limit is too high for the road). Every time I test drive a car I intend to buy, a ~40mph braking test is mandatory, even if the dealer is there (don't forget to warn). That gives you a good idea on the brakes condition (no swerving allowed on a level road) and ability. You won't be penalised if you can't beat the acceleration stated on the manual, but that 1 meter you didn't know you needed when doing 60-0 or 30-0, because you didn't spend extra on a good set of tyres, and/or didn't want to burn a little rubber on your braking test, will cost you dearly.
This should be demonstrated in driving lessons, i believe this kind of experience could reduce the amount of accidents around 10% - 20%. Some people doesn't pay attention about braking especially on panic situations, 80% driver would just slam the brakes. They didn't even calculate the brake portion between him self and people behinds. Even in the most dangerous incident i did not ever put the brakes pedals to the metals, because i also want people behind me had some space and times had the best decision to avoid an incident. Here's is the clause i made for you guys : (under control) "If you ever put the brakes pedal to metals it means you're drivin beyond the limits of your car, either your self"
5:00 Rotor size doesn't matter in breaking distance, tire width does. Bigger rotors fade less on heavy use, but wider tires have grater surface area to grip. So a mazda miata with 325 section tire will stop in a shorter distance than your M2 with 225.
S = v^2 ÷ 2a, so stopping distance increases exponentially with higher velocity meaning if the speed was doubled, the stopping distance would quadruple, also if the speed was halved the stopping distance would drop to 1/4 of its original length
The kinetic (moving) energy of a moving body is proportional to the square of its speed (KE = 1/2.m[mass].v.v), therefore higher speeds require considerably longer stopping distances, and brake heating rises dramatically. Put another way, if a car has 1 unit of energy at 30mph, it will have more than 5 units of energy at 70mph.
Been waiting for a new vid Mick, i have 2 questions/suggestions if possible. 1) Heel and toe, please make a vid about it! you're insane with explaining things and one of the only car enthusiasts that have been able to help me with things in the past. 2) How to drive a fast car you are not used to, been wanting to do a car hire/track day but in a gt3 rs or something like that, and my ford fiesta is a little bit different in power, not really sure how to transfer the skills over😂 As always love and appreciate your content man. Much love.
Thanks for the kind words! Two videos for you: ''how to drive fast in a manual'' - there's a whole section on rev match/heel-toe with footage of the pedals. I will do a full heel/toe video in future. ''how to drive powerful RWD cars'' - lots for you there about driving rwd for the first time/handling more power than you're used to. But 100% road focused. Short version is TC will save everything and don't worry, unless it's an old car.
Kinetic energy is proportional to the square of velocity (KE = 1/2mv^2), so doubling velocity quadruples kinetic energy. The brakes are tasked with dissipating the energy, not directly the velocity. This is why the stopping distance quadrupled when the velocity doubled!
I'd probably triple this braking distance. I start braking quickly but it takes me a good second to realize I need to do a full stop in a lot of cases.
Yo Mick I’m happy for you bro! The channel is growing you updated your car and you still making great videos 😎 btw you still using a camera attached to your cap while recording or you updated that too? 😜
7:50 no, normal cars won't go "50% further", 34 meters is actually pretty common braking distance for an average car braking from 60mph. Your big brakes don't mean anything, the tire is always the limiting factor, that's why ABS exists.
Car braking efficiency depends on weight distribution and suspension too, so that rear wheels will still do some braking still. So I believe there may be a difference. Yet you are totally right about brakes. Big brakes allow for several "high energy" brakings one after another. They can handle more heat and dissipate it faster. Also, good brakes allow for better brake modulation. But it does not matter for a single emergency brake.
Trying to impress someone with your driving...often ends up with someone having a bad day
Correct. Only person you drive fast for is yourself, never to impress, you’re with the wrong crowd if they get impressed by speed (unless on a track).
Very true. I learnt that the hard way unfortunately
@@Nitrousatoll I hope things ended (relatively) well for you lol. I nearly learned the hard way several times... I am very lucky I've still got my car and my mates.
@@MidnightGreen4649 it wasn't anything disastrous, just a tyre replacement on a B road in the dead of night and a broken shock absorber
@@Nitrousatoll that's good. glad it wasn't worse haha
Also, since no one mentioned it, watching a lot of car crash compilations on youtube and memorizing what conditions lead to most crashes makes you very aware to those look for those conditions when driving
The whole problem is no one wants to gamble with some idiots perception of things like that
True.
These cam videos are sad. Always half a story. The guy bleating on about someone under taking? Has been blocking the lane on a personal crusade for some sad reason 🤣
Most are cut short, especially on fb
@@despecc true as well as police pullover videos
DanDanTheFiremans motorcycles crash review compilations are one of the best hazard perception materials I’ve seen on TH-cam, very much agreed, watch crash compilations so you know what to look out for
Not even on a Sunday at 5am - there could be someone from the opposite way that also decided to go on a spirited drive. Just never drive beyond your sight/vision. It's risky.
It's actually funny because a minute before he said that, there was a pheasant running across the street. Now guess when wild animals are the most active.
Yeah and you are taking a risky decision not just for yourself but also another person.
Definitely, I would say I'm more comfortable and experienced than your average driver as I've been doing track days for years, racing etc... but even that can't prepare you for someone deciding to follow racing lines on a public road around a bend/corner or attempt to overtake at a bend that is essentially a blind spot. Unless I can see there's absolutely no one else on the road or nearby for a decent amount of distance, I'm not pushing into those 3 digit speed limits. That would be absolutely selfish of me.
As a youth in early 80s, I found that out 🤣.
Milk man 🤣🤣🤣🤣
I didn’t hit but it woke me up and I will never forget. I learned 👍
I regularly drive above 100mph but have never had an accident. Due to reading the road and not being an idiot. Slowing as I pass traffic. Before you judge? You don’t know if I can legally drive like that or not in uk?
Very true. I would also add don’t drive beyond your ability to that list.
I actually had to do basically this exact braking practice before getting my drivers license, in Sweden everyone has to do a driving exam where you slide cars around and get "reality checks" like what's shown in this video. It was a real eye opener when the instructor made us do a "moose test" at a high rate of speed but with a twist, the twist was that the cones were set up to have a route on both the left and right side of the "moose". The instructor would tell us which way to turn over the radio about 1 second before we had to turn but every single driver including me told the instructor that they told this information to us too late (in our minds, it felt like we had already hit the "moose" when he told us which way to steer). We then went slower and he did the same thing, this time every team managed to avoid the hazard. Reaction times are a real issue we all have to consider
Of course Sweden has a møøse test
@@NateSmith ...and for some reason, Canada doesn't make people do a moose test.
There's a cognitive difference between audibly being told which way to go, and visually seeing which way to go.
The true Moose Test is done when driving toward a barrier and a cardboard cutout appears on one side of it as you approach.
It's easier to respond correctly with the visual stimuli.
This channel is fire when watched at 1.25x speed
I'm on 2x 😎
0-60 in 48 seconds
i listened to your advice and forgot i put at 1.25x mid video and was wondering why the car was going so fast at 30mph lmao
LOL great advice
mad, before i even scrolled to the comments i literally put it on 1.25 😂
moral of the story is that public roads are not for racing, go to the track, as much as you try to control all the things you can , there will always be things beyond your control, even if its 1% risk/chance, that 1% can cost your life or someone else's
This is the correct answer.
There's more than 1% risk every time you leave your house
@@Smc-gm2nx no
5:20 This is actually a common misconception. Bigger brakes do not decrease your stopping distance, only increase the resistance to fade.
True, you can stop quickly on tiny drums if your tires are good enough. Applicable force to the pads is rarely the limiting factor except in large heavy goods vehicles, and some old worn out bicycle brakes. Otherwise you could say "I can stop faster because my leg is stronger" - an argument I've never heard for braking performance. The big discs are for accelerating and braking over and over again, where drums or smaller discs would overheat. It's also possible that from speeds of over 150 mph, you can overheat stock brakes in one fell swoop.
With more power utilized and downhill, you can put more kinetic energy into the car and take it out again, over and over. On the public road I'm more of a hypermiler, so drums all around would be okay for me. They don't rub as much and save fuel anyway.
indeed... This guy teaching people how to drive but he has fairly poor technical knowledge of cars actually
The 6 pistons clamping down on those big discs sure do though :)
@@MickDrivesCars Except they don't. Smaller brakes on an economy car will stop the car equally as fast as your sporty big ones. All what brakes do is lock up your wheels, from then on the braking performance is all dependant on your tyres and road contact, and external factors like road condition and weight of your car etc. It doesn't matter if they are big or small brakes, as long as they are sufficiently strong to provide the pressure needed to lock the wheels, which all modern brakes do, big or small.
The advantage bigger brakes give you, is that they don't fade as fast or overheat when you perform aggressive braking multiple times in a row. In an economy car, you'll (hopefully or you're driving poorly) only need aggresive fast braking in an emergency, so not often.
Think about it, if bigger brakes actually would make you stop significantly faster, all cars would be equipped with it, as basic road safety is paramount in the industry and not something that would be exclusive to sport cars (just like airbags, ABS, ESP, etc.). An economy 'normal' car drives just as fast on the road as a sport car, and needs to slow down just as fast as a sports car. Only difference is it doesn't accelerate that fast and doesn't need to do aggressive manoevres over and over again.
@@vahlokprime3175spot on mate. Same reason sports cars have drilled brake rotors, faster heat dissipation.
In germany we learn a handy formula in driving school. Your emergency braking distance (brakes fully applied) can be roughly calculated with: (Speed(kph) / 10)². So at 60mph (100kph) your emergency braking would roughly take up 100 meters. And at 30mph (~50kph) it would be 25 meters. Depending on the size of your brakes, this formula might or might not work for you, but for almost all stock brakes this is a good one to know. Drive safe everyone!
In south Africa if you leave a space in front of you large enough for another car to fit in you can be sure a car will take it from you.
In other words, at 30 mph, the stopping distance is about 6 car lengths for compact cars, 24 car lengths at 60 mph.
@@dammitdadSpace is a vacuum. In the UK it seems that people only think of the space in front of them as stopping distance and forget space behind them, cutting in front of other cars inches from them.
double the speed is usually 4x the distance as braking distance is proportional to the square of the speed. i wish this was something we actually learned in driving lessons and just overall physics of driving like weight transfer
the most i ever learned was how to correct a skid and even then it was useless info for anything not RWD.
they told you to lift off and counter steer which in a FWD car might not actually save you. Though I don't know if this is true if say, you hit ice, but at least in my sim racing, the best way to correct a FWD sliding is to put some power down to get traction off the front wheels. I once had to correct a slide in my AWD car which was the same procedure as RWD, but it was also low-speed. Wish I had some dirt roads to practise skid control in, or snow... maybe next winter.
@@MidnightGreen4649 yea i think skid control should be mandatory as well as full stop from high speed with and without abs. better yet get ppl to learn in long rwd cars and experience body roll and understeer and oversteer
@@nicktodorov669 Maybe we'd also get more young people interested in cars too. I made a sudden left with one of my friends in the backseat and once the shock wore off she thought it was kinda fun.
They do in Germany. This kind of stuff is part of the theoretical exam as well as some rules of thumb to estimate stopping distances at different speeds. One thing also thought is that there is a reaction distance (much longer than the simulated moving foot from gas to brake) because humans don’t react instantly. Additionally on narrow roads you should see twice your stopping time because oncoming traffic needs to be able to stop too.
They train you on all this in many EU countries
For that brake test, I recommend doing it down a hill. I tested my brakes for breaking distance, and the one time I needed to stop in an emergency, I crashed because it was downhill and the car did not stop in time. I even had video of it, and my reaction time was not the issue. Definitely tested brakes down a hill.
Fun fact bmw has a system when u take ur foot fast of the gas it shorts the distance on the brakepads so the when u hit it it instantly stops. Also on rain it shortens the distance so there is less water in the pads
Looks like BMW turns the hazard lights on automatically during a hard breaking event, I didn't notice him touching the hazards button.
If your watching this guy because you wanna drive fast don’t drive fast
this is very much true.. driving in highway is like 70mph braking on that speed seems normal from inside the car but its a fast fast speed. so breaking is must to know if you wanna speed. very good video! kudos to u mate
Once, in a parking lot, I tried to brake from 40 mph to 0 as hard as I could. I stopped hard enough to make me feel quite light headed. Ever since then, the only time I'm tensed up when braking is when I'm in bad traffic and a car's behind me haha.
Great video! I always say this It’s about your mindset and attitude when driving and how much control you have. Your driving literally tells the type of person you are not your car. Also when someone is in your car, you are responsible for that person
Well said!
"babe wake up mick uploaded another one"
hahahaha let's goooooo
That’s the case for me I love your videos
@@account-r3w me too
yessir
As always, great video, but I have a few fun facts to point out.
Sunday morning has less traffic, but probably more drunk drivers going back from parties, so I wouldn’t say there’s no chance of someone driving on the wrong side :)
Driving at night has a benefit of seeing someone’s high beams around the corner, so you actually have wallhack.
Your brakes are only as good as your tires. You could have Superman holding the rotors, but with no grip it’s just gonna trigger ABS anyway.
The less traffic there is the more likely there's wildlife around or that you'll be the first person to come across things like downed trees,big rocks or a washed out bridge.
Unlikely but I have seen them all.
I was a passenger when we hit a deer at night. It jumped out and did the classic deer in the headlights look.
Luckily we were in a Yank Tank and could drive home.
One day in Colorado we saw deer after deer crossing so I let the car behind me pass. Sure enough one jumped out between us but it was daylight and I saw it in time.
I've seen many branches in the road and one tree,many rocks and one boulder.
The scariest was being the first one to find a bridge washed out in the fog at night.
There'd been heavy rains and something just didn't feel right so I slowed down to a crawl.
There's bold drivers and old drivers but very few old bold drivers.
5 AM on Sunday actually can be even more dangerous btw. It's safe but can be another racer enjoying free roads ahead :D 2) can be a village tractor broken and without lights right around the corner or horses 3) drunk people heading home after a long night. But you know what I mean because the video is cool and you're telling the right things
Especially that part on doing a track day,it really helps you know your car well It's strengths and weaknesses.Because you will always be alert about what's going to happen rather than getting a nasty surprise.
In algeria we say: drive as if everyone around u is a bad driver, and any pedestrian is blind. this makes u account for any possibility anywhere anytime. You cannot imagine the number of times this mentality saved me. especially that drivers here are crazier and the laws are broken much much more than where you are.
10:00 Remember that you should be looking for potholes, too, in addition to incoming traffic or tractors. When you go over a small hill, you can see that there are no other cars but when do you actually see the road surface well enough to be sure that there are no potholes? If you don't want to break your car, you have to be able to stop before a huge pothole in the ground, too. You cannot assume that there's free lane to go around it.
In case of danger you should just forget the clutch and break as much as you can (you stop faster)
You might notice in the bloopers at the end I actually stalled on the 1st run because I did exactly that :)
@@MickDrivesCars The "double the speed 4x the distance" is something you do in physics class to learn about how kinetic energy works. the formula is (1/2)m(v^2), where v is the speed of your car in this case. if you replace that with 2v (so in this case you double the speed) you have (2v^2) which is 4v. since you come to a complete stop, the brakes have to dissipate all that kinetic energy, so at twice the speed the brakes need to remove 4x the energy in every case.
Also, tires play a huge role as stickier tires can prevent brake lockup and the activation of ABS. I only had ABS come on when I was braking hard and turning in the rain doing autocross. So either my tires were great or I was not fast enough :0
Great video mate! It baffles me the amount of people who drive right up the back of other cars pushing their cars to the limit around every corner regardless of the conditions or capabilities of drivers around them and somehow get away with it.
The truth is even basic modern cars have such high limits that your average driver can't get them out of shape
@@MickDrivesCars I should explain i meant specifically country road corners that are particularly sharp and usually in rainy conditions.
I did a safety driving course. One important tip about stopping distance is to count the seconds. Always be at least 2 seconds behind the car in front or any conceivable obstacle (find a marker by the road that matches the car in front and count one elephant two elephant). 2 seconds seems like no time, but a LOT can happen (and go wrong) in that time. Make it 3 seconds if you’re stressed or visibility is bad or it’s raining.
Cinetic energy goes up as a quadratic function (E = (mv^2)/2) so it makes sense that it was something like 4 times the distance:
E1 = m*v^2/2
E2 = m* (2v)^2/2
E2 = m*4v^2/2 = 4E1
nice pfp
That’s because the resistant work done by the brakes is Fxd where F is the braking force (assumed constant) and d is the braking distance. This resistance work must dissipate the entirety of the kinetic energy 1/2mv^2. Therefore:
d = 1/2 mv^2 / F
Hence the quadratic dependence of d on v.
You can also derive this from the equations of movement.
@@l-_-lShadowCat Thanks for complementing my answer! I hadn't completed the thought (nor had I the knowledge to), so I appreciate the help.
@@Dante-nu5cn You’re very welcome!
My driving instructor was very adamant about visibility, speed, road design and stopping distance.
He’s a fanatic too. Wanted me to use more power of the car :)
Taught me how to drive safely, and instructed me when I can let loose and use a little more juice (but not over the speedlimit. He’s an instructor after all).
This stuck with me and has kept me from getting into accidents.
And it’s exactly the type of stuff you’re teaching here :)
Tons of people driving fast don't realize that they also have to be prepared to stop and turn even faster. They never teach you these things in driving school, so most people are led to think going above the speed limit is dangerous, and the car, rather than the driver, is blamed when inevitably, people panic, freeze, and hit something hard and fast. I'm genuinely convinced that beyond airbags, ABS, TCS, and ESC, car safety systems are kind of useless. Ah, and crumple zones and whatnot are also nice to have too, up until it means your beloved car is totaled.
I always have a personal rule which is to drive in a manner which makes my passengers feel safe. Inevitably I wind up putting them to sleep lmao.
I'm a car guy, owned a dozen cars over time.
Occasionally people recommend me cars because of their crash safety features. I'm like - wouldn't you rather avoid crashing in the first place?
Most people treat electronic driver aids as the foundation of their driving skill.
@@JayMaverick There IS a benefit- lower insurance! I am lucky that my car's driving nannies don't interfere with the fun much, and so I don't really bother turning them off except for the stupid lane keep assist. If it's found that you disabled any safety system then insurance will probably screw you over. sadly that's the nature of the game.
My parents were concerned about the crash safety of my WRX (which is really funny because they got it new for me as a high school gift) because it was a sedan... the thing is so stable through corners it scares me, and the brakes for a car built from the parts bin are great on the street. Feels much safer than any other car I've been in, save for my friend's dad's Tesla. And that thing feels safe just because he's a very experienced driver.
@@MidnightGreen4649Exactly, I don't get the discourse around safety features being "intrusive." You really mean to tell me that automatic emergency braking, cross traffic warning, pedestrian detection, so on and so forth are actually intrusive in your day-to-day driving? And is it really that hard to use your damn turn signals to stop the lane keep assist from kicking in? I don't personally have these features, but I feel much safer on the road knowing that the 5500lb Ford Expedition behind me won't kill me in a rear end collision if the driver is busy yelling at her kids in the back seat.
@@d47000 You must not have read my initial comment then. In MY car I have not noticed them intrude on my driving. I would rather do without them, as the mere knowledge of these safety systems' existence affects your behavior and attitude towards driving the car itself. In my opinion that change makes for more distracted drivers who assume the car will compensate for their abilities. In my car specifically, I do not drive in a manner where the systems activate and I consciously feel it. So as far as I am concerned it does not matter to me whether they are on or off.
In the end, and I say this as an engineering student, the optimization of one quality will inevitably impede on other qualities. In just about every practical case... that's not good at all in product design.
As far as lane keep goes... there's times when you do need to cut the line slightly and it would be silly to give your turn signal. For example, road work. Some systems also do impede driving in cars because they are predictive, and it's hard to accurately predict 100% of the time when a crash will occur... so you have models built into the software that tries to account for that 99% and sometimes you do get a 1% false positive, or even worse, a 1% false negative. If the safety system is never active then you are probably a good conscientious driver. But Karen arguing with her demon spawn will find a way to rear-end you even with her car being designed to not crash into anything.
sleepy passengers are the pinnacle of a great driver
I didn't catch it in the vid, so I wanted to emphasize how important to distinguish the difference in braking distance when you have really grippy tires vs hard tires. From the factory, your brakes are designed to apply more than enough force for any emergency stopping situation at least a few times consecutively before overheating.
Entertaining and high quality content as always thx for the upload! ^.^
Even at 5am on a Sunday morning always drive within your viewable stopping distances....never drive in such a way that risks others.
The overall message in this video is extremely useful....and I wish a visit to a test track were part of obtaining a driving licence where stopping distances and real car control could be experienced.
Its wild that not once was it ever mentioned about the car behind you
here in the US where theres a lot more traffic the chances of being rear ended is way higher than in these roads with no cars
Cars don't tend to catch me from behind :)
I would argue that the UK roads are far more congested than US roads.
@@ptb2008lol you must not live in a city with a dense highway
EK=½mv²
Increase in velocity has a massive change in the kinetic energy.
I realise this is a very basic way of looking at it but it gets the point across
I have him sim racing settup and to be honest it’s taught me so much that’s saved me more than once on the road
Me too, but reality and sim racing are two completely different things, and I would be extremely careful about over confidence driving, because you’re a good sim racer.
your voice is poetic! hooks my mind and all you say directly gets into the head. Even when english is my second language.
Damn, that's high praise! Thank you
The Sunday 5 am example goes both ways, there might solve some Saturday night out dude thinking the same under the influence of alcohol, I saw a study most accidents happen during early mornings of Sunday, it’s best to have a visualization of how much you can control instead of relying on low traffic.
Practice...practice...practice... Experience is your best ally just like most things. Knowing your car is paramount so you understand your limit vs car limit and finally, most importantly, understand anything can happen and when it does, there's no magic trick. The faster you go, the bigger the consequences. Whether you are responsible or not, more speed = more damage. Let that sink in and you'll naturally allow yourself wider margins when having a little fun, not just because you have a good understanding of where you're at but also because you have no idea where everyone else is at. Experience just helps you anticipate/react better and read other people's state of awareness and/or mindfulness. When you come around a corner, all bets are off. It doesn't take much speed at all to generate lethal force with a fat heap of metal. I love driving. Always have, always will. Posted speed limits are not my religion. However, I try to remain very mindful of all the above factors and it keeps me on a fairly tight leash, naturally. It doesn't matter what you're driving. The unspoken rules apply.
Conversely, experience can also be our worst enemy. Where I am from, experience tends to lull people into complacency, especially if drivers see other drivers successfully cutting into lanes (& successfully brake in time to avoid accidents). Most of the time, it is only when one has been in an accident or been in a close call that one realises how easy it can be to get into an accident.
@@matthewlee7405 For sure. I am however specifically preaching experience in mindfulness which goes a long way to making up for all the npc's out there and more generally minimizing risks that go hand in hand with the operation of a motor vehicle.
one thing that causes a lot of highspeed crashes is when your in a difficult situation and you take to long, precisely, (less than a second) to decide what cut or what your going to do to get by upcoming traffic. I see a lot of guys hesitating a lot on there decisions when theyre swimming or cutting through traffic and that's an easy way to crash.
“People say I shouldn’t drive so fast on this road since there are driveways and someone could back out and hit me, and they’re right (but imma do it anyway 😏)” me too man me too, I can tell you and I have the same passion for driving, I think just like you do, keep up the videos, love em!
When I was younger in my teens I was more reckless but in my mid 20s, I personally just don't have that much trust in other road users. Someone can decide to overtake at a bend or think they're following a racing line and use the opposite lanes, I only really hit those extremely high speeds if the roads are absolutely clear and I can clearly see there's no vehicle around. If it's a long straight and no opposite traffic then I'll absolutely put my foot down but if there are a lot of bends where visibility isn't 100%, it's not that I don't trust my own abilities because I do but I don't trust others to not do something stupid.
Golden rule: You must always be able to stop safely on your side of the road in the distance that you can see to be clear. In situations where you share the road with oncoming traffic this should be half the distance.
Brow of a hill, limit point on a bend, heavy rain or fog, vehicle in front, darkness... those are all the distance you can see to be clear.
Magazine 60mph-0 distances (usually 30-35m for production cars) and 70mph-0 distances (usually 45-50m for production cars) are good indicators. You will need a heck of a distance to slow down from 120mph which you will hit on some stretches of straights on b-roads. Also, you don't always need to brake to 0, if you spot something out of your current calculation (seeing some light, objects on road, some car coming out from a side road etc), you can always slow down to a comfortable speed and speculate. Always see far and look at the direction you want to go.
There are also lift off/snap oversteers for newer drivers, changes in road cambers, changes in elevations especially during bends, bends that get tighter, these kind of things can really throw you off when you are speeding. Rain/puddles/sand/wet leaves/snow/ice/oil slicks will amplify all situations. So yes, always start slow, then speed up, real life driving is not a video game where you can rewind or repair everything with game credit.
5:22 The car will not stop a lot quicker, it's brakes won't fade as fast, almost all brakes on consumer vehicles are capable of locking up the wheels (unless they weren't serviced) and ABS will kick in before that to keep it at peak deceleration. the most important variables on your stopping distance are traction and the ratio of vehicle weight to the contact patch of the tires
this is really good and informative even for people who don't purposefully drive fast. every driver should watch this
last technic, you are a goat, you disable abs and you master the out of braking without wheel locking :)
New to driving, learning a lot from this channel. Subbed.
"5Am on a Sunday morning gone out for a drive and you want to enjoy your car" probably the most creepy thing i have heard this week 😀
Bottom line: go to the track once a month and you will naturally go slower on public roads. Everybody wins and nobody's hurt.
Nice demos, I will try to get my young son to watch the channel and to also subscribe. My driver friend and me have almost come to serious grief when driving down a gravel mountain road, when his wheels locked up, instead of counter steering, he tried turning with the slide, and we ended up perched halfway off a 300-metre drop. Cheers.
Also hills are something else to be aware of if you might have to slow down faster.
Even if you have enough distance to stop at your visual limit, the other car also needs that same distance, so you would need double the distance. Just slow down and I also think you need to try the anti-lock brake and see if it is better at stopping.
Yes Tires!
I know this is probably not a major issue for you but for me where I am having tries that are good in the winter or in mud are essential... don't cheap out, buy decent tires😊
6:30. Double the speed, 4x the distance is correct. The brake's job is to dissipate kinetic energy (speed) as heat. When you are going double the speed, you have four times the kinetic energy since kinetic energy is 1/2mv².
One point that wasn't mentioned is that if somebody is overtaking and coming towards you, you have to at least half the distance, so the other person can stop too. This is especially important on smaller roads.
It’s funny to notice that the volume knob is on the passenger's side, unlike in left-hand versions of the car. As a driver, I have volume control on the steering wheel, but my passengers have to reach over to the driver's side, which is quite inconvenient
Mashing the brake to 100% and triggering ABS definitely contributed to the 4x braking distance.
But yeah, active critical thinking is the key. I genuinely don’t understand how someone can send it with their brain relaxed…
It's funny, I made a video a long time ago about braking and how you should progressively load the front suspension to get maximum brake efficiency. People told me I'm an idiot and just mashing 100% and letting ABS take care of it is faster :)
I made a conscious decision in this video to not do it ''properly'' but rather brake as someone might in an emergency. I recon sub 25m is possible if I got the tires/brakes warm and did it right.
@@MickDrivesCars Well, seems you’ve outgrown those people lol. Threshold braking is King.
Good choice for the video, though, as not everyone will have experience with braking to just before your ABS kicks in/will want to practice and familiarise themselves with it.
@@MickDrivesCars You did it right. I heavily doubt one would be able to do a proper threshold braking in emergency conditions, its just too much stress. May be after a sec of ABS braking confident driver would find enough courage to lift the brake pedal a bit, donno =). 1st normal reaction would be emergency braking and thats ok I believe.
Seeing this days on my recommended after the death of 1stock😢. Sip🕊️
Great video for youngsters.
In the 80s in my XR3 van, twin carbs& fast road cam btw; I was having fun at 5:00AM. Roads must be empty…….bar bloody milkmen 🤣. Close, but ok.
At 100mph +to 156mph, I’ll speed on an empty stretch. As soon as I am overtaking, I slow to a stop/avoid speed as the traffic I am passing could do anything. Maybe something worth filming?
Clear again, foot down. (Run flats on AMG Estate btw before someone says blow out) yes I have had blowouts on other vehicles and motorcycles. Front on a bike is fkn hairy. Stayed upright.
Another thing, tailgating is bad. You are better cautiously undertaking than tailgating someone that refuses to move over when there’s no reason to be in that lane.
Ice throws another wild card. Be aware if you are climbing a mountain in winter for black ice. Only time I have crashed a bike. I was also taught how to drive on ice including skid control.
If in doubt and you loose control, so long as impact isn’t imminent, just take your feet off and steer.
No abs, eba etc then. Also lectures off cops which is now sadly lost to £££££ I learned by those lectures.
Since 1984 passing my tests, I have never had a serious accident. Ice was something where I lived. A beautiful twisting road ascending more than you think with a stream at the side. Where I crashed was where it crossed. Mist had created black ice across a hairpin double bend. Lovely dry cold day otherwise.
In the summer on a bike, you can ride 70-100mph (I was younger then and roads were a lot quieter)
You could drive on a Sunday morning, 20-30 miles and not see another vehicle then. Driving was enjoyable then.
Speed doesn’t kill, driver error and speed in incorrect places does.
thanks for the tips ... stay safe out there !!🥰🥰😍😍😍
Love your communication skills and your content, and the M2!!! Keep up with the videos!
Thanks
Damn, thank you!
Practicing braking is actually very important.
9:38 Is it just me, or these narrow two-lane roads with high-hedges on either side, feel very stressful to drive fast on?!
12:08 it takes 2 people who are out on that quiet 5am sunday morning who swerve into the oncoming lane on a corner for a very grim outcome.
One time I was driving on a highway behind a truck and got to a part of the road that's totally straight for a while, allowing great visibility to pass. There were some cars coming, so I waited then, the opposite road completely clear I switched lanes only for the truck to shift over too as turns out there was a bicyclists riding on the side. They were completely covered by the truck so there was no way for me to see or expect it. Luckily there was enough shoulder for me to halfway drift off and I also sped up to quickly pass as I was right by the truck as that point. So even when doing everything you can there can still be curveballs. Now I keep in mind how much shoulder there is as well when I pass in case I need it.
Oh my God there is so much common sense in this. Drive safe!
This is so calming and helpful
that RPM HUD is lit
Very educational, thank you!
This video was very informative!! Thanks ...
Glad it was helpful!
Kinetic energy is equal to 1/2 • mass • velocity squared so double the velocity is exactly 4x the kinetic energy the brakes have to dissipate, so yeah double the velocity is 4x the braking distance (assuming energy dissipation is the limiting factor and not traction etc) 😊
Good advice, how about having your headlights on during the day? Small dark car can be difficult to see in strong sunlight and deep shadows.
Kinetic Energy KE = 1/2 MV^2 So when the velocity increases your KE is going exponentially higer with V^2
So if you double your speed your stopping distance quadruples since your breaking power remains constant for your car regardless of your speed.
Bro what a top G. Video. Subbed
Great video, Mick! Definitely a must-watch for beginner drivers. It's sad that on the driving lessons (at least here in my country), they don't mention 90% of the stuff you've said in this video.
I really love the content you do
Very life-changing advice 🤯
Also, with manual, ofc we usually go in the highest gear, however, if you get to have the ability u can use ur gearbox to emergency brakes, be careful dont blow ur gearbox going into a too low gear
5:11 Stopping distance does not depend on size of your brakes/brake pads and only depends on your tyres (grip) as long as your brakes can lock the wheels. Larger brakes are only useful when you brake a lot in a short period of time as they are harder to overheat.
Bro wtf happened when you counted meters "2...4...6...8..." HAHAHAHA WHAT 😭😭
Amazing vid man, can help a lot of people who are starting out for sure!! Be safe everyone, but don't forget to be fast when conditions are good 😝
6:23 It has something to do with how kinetic energy is "created," since the formula (Ek = 0.5mv^2) has v^2, exponentially increasing energy with a linear increase in speed.
but your momentum is proportional to your speed,
mass × velocity
@@saminaham8251should've written it like this: Ek = 0.5m(v^2)
Best thing to do according to me, practice on a driving simulator with heavy traffic
11:00 Remember that people pulling to the road are expecting other road users to follow traffic rules. If you brake the law, be prepared to be the one that is responsible for every action on the road. And think about the possible consequences before taking those extra risks.
Great video! Thanks Mick
Great video and topic! Thanks :)
As a fellow BMW driver, I approve of this message. My driving may at times seem erratic to others but I am fully in control and have calculated the location, direction, and state of the vehicle now, and 10 seconds into the future.
The number of people who have said this and then crashed is crazy
These are the most essential skills to stay safe when driving fast. Even for normal driving they're helpful (yes, it's rare but sometimes the speed limit is too high for the road).
Every time I test drive a car I intend to buy, a ~40mph braking test is mandatory, even if the dealer is there (don't forget to warn). That gives you a good idea on the brakes condition (no swerving allowed on a level road) and ability.
You won't be penalised if you can't beat the acceleration stated on the manual, but that 1 meter you didn't know you needed when doing 60-0 or 30-0, because you didn't spend extra on a good set of tyres, and/or didn't want to burn a little rubber on your braking test, will cost you dearly.
This should be demonstrated in driving lessons, i believe this kind of experience could reduce the amount of accidents around 10% - 20%. Some people doesn't pay attention about braking especially on panic situations, 80% driver would just slam the brakes. They didn't even calculate the brake portion between him self and people behinds. Even in the most dangerous incident i did not ever put the brakes pedals to the metals, because i also want people behind me had some space and times had the best decision to avoid an incident.
Here's is the clause i made for you guys : (under control)
"If you ever put the brakes pedal to metals it means you're drivin beyond the limits of your car, either your self"
great channel mate...Watching you in Bosnia too
5:00 Rotor size doesn't matter in breaking distance, tire width does. Bigger rotors fade less on heavy use, but wider tires have grater surface area to grip. So a mazda miata with 325 section tire will stop in a shorter distance than your M2 with 225.
!!! Right on
S = v^2 ÷ 2a, so stopping distance increases exponentially with higher velocity meaning if the speed was doubled, the stopping distance would quadruple, also if the speed was halved the stopping distance would drop to 1/4 of its original length
The kinetic (moving) energy of a moving body is proportional to the square of its speed (KE = 1/2.m[mass].v.v), therefore higher speeds require considerably longer stopping distances, and brake heating rises dramatically.
Put another way, if a car has 1 unit of energy at 30mph, it will have more than 5 units of energy at 70mph.
How to avoid crashing when driving fast:
Step 1. Don't drive fast and follow the speed limit (it's there for a reason)
Those m2 brakes are incredible
Been waiting for a new vid Mick, i have 2 questions/suggestions if possible. 1) Heel and toe, please make a vid about it! you're insane with explaining things and one of the only car enthusiasts that have been able to help me with things in the past. 2) How to drive a fast car you are not used to, been wanting to do a car hire/track day but in a gt3 rs or something like that, and my ford fiesta is a little bit different in power, not really sure how to transfer the skills over😂
As always love and appreciate your content man. Much love.
Thanks for the kind words!
Two videos for you:
''how to drive fast in a manual'' - there's a whole section on rev match/heel-toe with footage of the pedals. I will do a full heel/toe video in future.
''how to drive powerful RWD cars'' - lots for you there about driving rwd for the first time/handling more power than you're used to. But 100% road focused. Short version is TC will save everything and don't worry, unless it's an old car.
@@MickDrivesCars Much appreciated brother, gonna watch these now, looking forward to more coming from you
Kinetic energy is proportional to the square of velocity (KE = 1/2mv^2), so doubling velocity quadruples kinetic energy. The brakes are tasked with dissipating the energy, not directly the velocity. This is why the stopping distance quadrupled when the velocity doubled!
Very interesting. Have you done this jamming on the brakes, what is called a panic stop? Thanks!
Good stuff!!! Thank you!
I'd probably triple this braking distance. I start braking quickly but it takes me a good second to realize I need to do a full stop in a lot of cases.
Yo Mick I’m happy for you bro! The channel is growing you updated your car and you still making great videos 😎 btw you still using a camera attached to your cap while recording or you updated that too? 😜
7:50 no, normal cars won't go "50% further", 34 meters is actually pretty common braking distance for an average car braking from 60mph. Your big brakes don't mean anything, the tire is always the limiting factor, that's why ABS exists.
Car braking efficiency depends on weight distribution and suspension too, so that rear wheels will still do some braking still. So I believe there may be a difference.
Yet you are totally right about brakes. Big brakes allow for several "high energy" brakings one after another. They can handle more heat and dissipate it faster. Also, good brakes allow for better brake modulation. But it does not matter for a single emergency brake.
@@Vivicect0r Good points.
Stay safe, you and don't put in danger to other people
best video title ive seen in ages, straight to the point LMAO
