Using a dirt bike to show different stuff on a car is super smart and I hope you keep doing it. It has a easy to understand simplicity but still explains what is happening accurately.
The gen2 prius literally had an electronic braking system. It has a stroke senosr that simulates the feel of a conventional braking system. Low speed and emergency braking is the only time the hydraulic brakes operate. Thats why they don't need their first brake job until well over 100k miles with normal driving habits.
not sure what happened, but my friend's new Corolla just lost the brakes at a stop light, no crash, but he had to have it towed to Toyota and they had to replace $3,000 of the "brakes" under warranty of course, so even the old hydraulic brakes can fail on a new car.
Electronic foot brakes might not be very common but electronic handbrakes are becoming much more widespread. I definitely feel a lot safer with an old fashioned cable handbrake...
Every time you pass a car bq on the freeway. Also current steering is hydraulic assisted steering. True hydraulic steering is only available off road as there are no pitman arm down mechanics.
BMW had that system in the R1150rt for a couple of years. It was a disgrace as it wasn't very fine tunable so many people would be dropping the motorcycles when trying to ride the rear brake.
My dad once parked at a place where some gangsters didn't like that he could see into their office. They cut the break wire, and my dad started to reverse into a bigass gap, now he's dead. Just kidding, he could stop with the handbrake, he died of colon cancer.
Actually we got electric brakes in 400 ton dump truck. But they are built to be safe. Basically there is huge ass spring applying brakes all the time and there is huge ass electric bit that prevent spring to apply brakes all the time so you can move. Basically in order to drive you need electrical power in order to stop you need nothing, just remove power from electric bit and brakes are at full stopping power. Not sure if that would be smart on 200km/h car but on slow dump truck is perfect
It's no worries if you lose power with electronic breaks! As Audi describes, if you lose power, a check valve means your electronically controlled breaks are now regular old hydraulic brakes, and your foot does all the work again. Phew! 😅 And, electronic brakes have the added benefit of being able to stop with the brake fluid boiling, as they can pressurize the "air" enough to stop the car, versus a brake pedal which just hits the floor, and then you're done. Neat!1!1
I think I remember an F-22 test pilot giving a lecture and mentioning the new fighter jets had the control stick not move at all, it would sense the pressure the pilot exerted on it, and how it was really weird for the human pilots and they had to design sticks that moved.
I may be incorrect, but I think this was something first tried in the F-16, and since humans are better at knowing the position of our limbs than how much pressure we're exerting with them, they found it was more intuitive to build some movement back in to avoid feedback loops of pilots overcorrecting errors. I wonder if the f-22 control stick was identical! My source is "The insane engineering of the F-16" by Real Engineering, around 22:30.
As the video said, there are several perks, and also: 1/ electric brakes can stop the car even if there's hydraulic failure, and redundancy is good for safety and reliability 2/ it can be controlled electronically that might be able to assist with self-driving 3/ regenerative braking can improve fuel economy
I worked in electrical technology in my high-school a year ago and what I've learned is the more simple and tough you can make something the more reliable it will be
@@vbence12 Feels fine to me. Newer cars have a short traveling brake pedals that feels stiff. The G29 replicates that perfectly imo. Only older cars (90s and back) have spongy further traveling pedals.
@@TylerN945 they are fine, more than fine they are great. But breaks, even modern ones, are pressure operated and provide (at least some) feedback based on the tire grip and break staus. Which can't be replicated with simple potentiometer and springs.
That’s why you drive a manual. Just moneyshift into first and you’ll be stopped reeeaaaal quick. The amount of people thinking I’m serious about this as a legit strategy to stop is hilarious.
Also Germans: let's place here and there a non standard screws so no one can repair it in the field without proper screwdriver. I just "love" how they over engineer something simple 😂
I like the title and the explanation of the basics. There's even more to it: In May 2004, Mercedes recalled 680,000 vehicles to fix their complex brake-by-wire system. Then, in March 2005, 1.3 million cars were recalled, partly because of further unspecified problems with the Sensotronic Brake Control system. If the electrical break failed, they had a classical foot driven hydraulik backup, but only to the front wheels and without the typical vacuum servo assistance. That happening without pre warning resulted in way longer brake distances, subsequently leading to some accidants of almost brand new, well maintained upper class cars. In 2006 they discontinued the system in the E- and S-class limousines. Secondly: There were cars, that had no direct hydraulic connection from the break pedal Movement and no feedback at all: The Citroen DS and CX upper class cars had just a foot controlled, spring loaded hydraulic valve for breaking. A single belt driven pump provided hydraulic pressure for the breaks, the clutch, hydropneumatic suspension including the dampeners and for the power steering, that also had no mechanical connection to the steering gear (but a mechanical fallback with extremely wide dead clearance) . Buyers loved the lack of feedback, testers hated it. They sold 2.5 Million from 1955 to 1991, not so bad for upper class cars of legendary complexity and maintanance costs. If the pump failed, there were several storage tanks, that provided full usability for some more minutes. For example after 20 times of breaking, it stopped working and you were left alone with the mechanical handbreak with litereally coin sized brake pads (on the Citroen CX). The system worked surprisingly well, the safety record was flawless.

Regenerative braking can actually be done so well, that you hardly use the regular brakes at all. In fact, if you press the brake, it will also regen brake first. One pedal driving is a common thing in EVs. You are just using the actual brake calipers when you have to brake more in unexpected situations, or you just driving faster, requiring more brake power to stop for the red light.
Agree to that. Regen braking (especially if you have front motor) can cover 99% of traffic situations. New trend for electric commuter cars is to reduce max speed anyway, so all that means that brake overheating will not be an issue. Ventilated disk will not be necessary, brake calipers and pads can be also made smaller and lighter. Additional bonus is the reduced unsprung weight... Of course, with performance cars, it is another cup of coffee :-)
@@drazenradosevic7467 Normal size pads still needed for emergency situations, but you basically never need to change them since they are rarely used under normal driving. The Model S Plaid under full breaking from top speed to zero, even with regenerative braking to assist, the calipers get very hot. This is a bit of an extreme situation, but there is a need.
This is the answer of when electric brakes will be common on cars. It will only happen after the majority of drivers are driving EVs with regenerative braking. Once people get used it, and get comfortable with regen braking, they'll be more receptive to fully electric system.
"now electrical failures, we see those all the time" So lets make one of the most important safety systems on a car electrical vs hydraulic which rarely fails. Brilliant!!
"because we aren't that familiar with hydraulic failure" as someone who's driven plenty of 20+ year old shitboxs in the rust belt I'm pretty familiar with it
Honda and Toyota use completely plastic coated brake lines. Just something to think about. I've got a 15 year old relatively rusty Acura here. Brake lines are pristine.

@@krisg822 as an American former ASE master certified automotive technician, I can testify to what I’ve said out of experience. I’ve even owned at VW that hit 160,000 miles, and suddenly cost me a minimum of $400 usd in at cost parts per month for 4 months (not including labor, before a tiny chain slide let loose and bent valves. I fixed it, sold it, and that winter it returned because the brand new pcv system froze over in a garage and pressurized the crankcase, blowing the front main and ruining the timing belt. This was the norm for many VAG owning customers. If it’s not leaking oil at 60,000 miles, it’s probably out of oil. Conversely, I’ve owned and serviced so many American made cars and trucks that have made it over 200,00 miles without the need for major repairs. I don’t care what award a car company bought, I just care about real world high mileage reliability on the used market, therefore I own an Asian car
@@davidelzinga9757 the reliability of the cars i mentioned was based on their users experience; you may be not aware of that, but VW parts in US are much more expensive than in Europe, and US parts are more expensive in Europe than in US. So after a PCV valve got replaced (or a system for that matter) it froze, so not the old one but a new one = installation error? then again, my mother refuses to get a new car and drives a VW Golf 4, that thing is from 2002 and has 280 000km; now the winter was kinda hash and the temp went at some -29*C , not sure if the valve in that very engine is called PCV, but same sort of valve froze and about 4 liters of oil went out through the dipstick hole....yes the dipstick turned into a projectile. Refilled oil, it runs again. The reason why this happens is bcoz my mother does not drive the car too often and only few kilometers at a time, i doubt that the oil ever reaches more than 50*C temp, this means, quite a lot of condensate water collects everywhere. The thing with the oil happened in 2018, the car still runs to this day.
Although the electrification of cars excites me, I can't wait for things to come full circle and for people to sell cars with mechanical systems as a 'premium' feature that feel 'authentic' and 'analog' lmao

This is very dumb. Electronic systems are inherently more reliable than mechanical systems, failures of electronics are failures of software, but not at all software is created equal
@@annacrow9716 failure is failure. Period. And in my experience with consumer electronics they absolutely fail at far higher rates than older mechanical systems. They are designed to fail not last. The idea is to sell more not sell one.
Its hard for a electronic system to be justified if it can't beat a incredibly reliable, simple, and cheap mechanical system without offering some new useful feature.
Especially when that electronic system would fail with every other electronic system on the car. The reason hydraulic brakes stick around is because their mechanical function is completely independent from the alternator.
there are some advantages actually. better automatic braking is one of those, but one thing that i wished they had mentioned was advantages in the event of brake fluid boiling. your brake pedal can only travel so far but an electronic pump can just keep pumping fluid until it moves enough fluid to stop the car. i watched one video on the c8 corvette where they talked about that. obviously, you can’t just keep driving with the fluid overheating, but it’s enough to stop the car in the event of such an emergency.
The brake system is complex, expensive and messy. Just think of manufacturing and placing all of those brake lines and having to fill them with messy fluids. That, and electronic brakes offer a bunch of new features, regen blending and adaptive braking effort being two big ones
@@thomgt4 and then there is the problem of electric brakes can't apply enough force as efficiently as simple hydraulic brake systems. There is a reason major industries only use hydraulics for certain things.
Yeah no... You mentioned how brake lines leaking are an issue with the "old" style of brakes, but that isn't fixed either with e-brakes. And you said it was simpler? What?? These are the same parts + now you've got position sensor, computer software, servos, cylinder to simulate feel, ... This isn't simpler... Not in the slightest. And is totally unnecessary for most people.
No no. Audi's ebrake system is not the system he was talking about when he meant "fully electronic". He was talking about an actually fully electronic system with no mechanical parts, where an electric motor would clamp your brake caliper onto the rotor. The current braking method does have issues with leaks and whatnot. But nothing that happens usually within the first 5-10 years of the vehicles life span.
@@NaddlyC well shit, solid argument. putting a electric motor on each caliper seems ridiculous. electronics and heat dont mix well. well you have a motor creating its own heat plus the heat of the brakes your asking for a failure.

Indeed… I had an SM, which had the same system. These cars had a high-pressure hydraulic pump that actually supplied the pressure. Your foot on the “mushroom” simply opened a valve. Yes, we got used to it, but these were by no means sports cars… It is the equivalent of a steering system that gives very little road feel. There was an accumulator in the system, so that you still had a pressure reserve in the event of the engine quitting on you… which the Maserati V6 had a anasty habit of doing, in very bad ways…

@@blakeyboychar Toyota still uses 20+ year old designs in their vehicles. That's why a Tacoma still has a handbrake, drum brakes, the same Bilstein shocks since the 90s, a transmission which came out in 2002, and an engine that's also from the early 2000s. Granted, those designs are slightly modified, but at the core they're still the same. Sure they have added a lot of electrical stuff to it as well, but mechanically, those vehicles are ancient. Even if the electrics fail, mechanically it'll keep working.
Basically already is. Imagine how terribly an rs6 will handle without it's active air suspension, active damping, rear wheel steering, and active anti roll system.
Same, tho I love how they said "certified" autozoner. That would be literally any of us lol. Also, the fact they had a red shirt do it instead of a gray was kinda odd
Brakes will always need a backup system. As in power brakes and power steering. Parts critical for the safety just need a working manual override. BTW, about no power situation: it's actually solvable. Think of the brakes that are "normally closed" and you need to actually provide power to lose them. The hard part is to make it energy efficient and fast at the same time.
“The scariest thing is wanting to stop but not being able to.” Yes! This has happened to me several time with my 2003 Ford E350! It has huge duel piston calipers at all four corners and requires an extra belt driven vacuum pump on the front of the engine to help the normal vacuum booster for the brakes. In my 18 years of ownership, Ive flown through a few stoplights and into some ditches when that stupid pump fails. Your butt seriously puckers!!!!
The reason hydraulics stick around is simple: When the engine fails, they still work. When the electrics fail, they still work. That's the point. And that's also the reason handbrakes have stuck around: Because a cable/rod driven handbrake is your last resort when hydraulics fail, and yes, I've had to use it in that situation.
same i had problems of low brake fluid pressure in the brake lines before and had to rely on handbrake in those instances, so your explanation about the isolated forms of failsafes in these systems and not being codependent (if everything is electric and the battery dies then everything doesnt function) is important reminder as to the necessity of keeping the function of these different systems seperate and isolated from each other, Slam Shift with the best answer imo

I have a great idea for brakes, I’ll design a transmission that makes it so when you push the clutch you can put it into reverse so you have the power of the whole engine to stop you, I call it the transmission destroyer
I think this would be possible if your reverse gear had a synchroniser, but I’ve never heard of a car that does. Most cars don’t, hence why you have to stop fully before sticking it into reverse
The Nissan Leaf does this in an admirably simple way: the master cylinder is just set back about an inch and a half from the pedal arm, so the first 2 inches or so of pedal travel are just an input to the computer asking for regen braking, but if you push further, you hit the master cylinder and apply the friction brakes. so even with no power (12V and traction battery disconnected) you still have conventional braking to stop the car. The power steering works the same way, just with an electric pump instead of a belt driven one.
Thats why I like 90's and early 2000's cars the most, they have just the right balance between not being carbeurated but also not scull fucked with expensive shittly made electronics

100%, even in the late 90s you can get EFI, OBD2, ABS, dual front side airbags, etc. depending on the car. Into the early 2000s some also had lane departure and auto braking. I think the modern era of tiny turbo-charged engines and luxury=electronics in particular is a downward spiral.

This seems like audi all over. Tech: I have a brake system for the car. Designer: I see but we want complicated, we need to charge people lots for useless tech that only we can fix so we can charge them to service
I had my brake line burst on my Silverado coming up to a red light @ 50MPH. F'n terrifying. Was able to jump on the shoulder and pump what was left of the brakes before hitting intersection. So hydraulic isn't perfect either. For electronic brakes, you would absolutely need some form of fail-safe system like railway air brakes. So that if all power is cut, the brakes are applied. An example could be a spring powered clamping brake pad that's held open when there's power but clamps disk if power is lost. Would really suck having car suddenly stop by itself but way better that suddenly zero brakes, I can attest to that personally.
Handbrake? Or is it 'E-brake' in US? Which I thought meant electronic, but means emergency in that case? So now if your electronic brakes fail, you still have hydraulic, and if they fail, you have e-brake, and if that fails, you can engine brake shifting down, but maybe not if you're using automatic transmission. Simple....?
I think electronic breaks should be designed in a similar manner to air breaks where breaks are automatically applied when power is lost. Though my preferred braking system is mechanical breaks.
So, if for some reason you end up with no energy in the middle of the road... How do you, you know, push the car to the side of the road, for safety reasons?
I think the benefit is the computer can slow the car with regenerative braking so the brakes last longer and you get a slightly longer range. I’d rather do regenerative braking manually either with a separate lever or just sticking it in reverse while still pushing the throttle like with electric forklifts
@@lazarustheatv8389 re: "I think the benefit is the computer can slow the car with regenerative braking so the brakes last longer and you get a slightly longer range." not so much, that's for BEV's with an electric motor. in contrast the Corvette C8 is full ICE (for the moment at least) but indeed has the fancy "quasi electric" braking you're all talking about.
JERRY! I don't like what you said about regenerative brakes either! It's not driving the motor in reverse! You should really know that electric and hybrid cars still use transmissions, the motor is either on the other side of the transmission, or in the case of hybrids, between the engine and transmission. Regenerative braking works by building a generator into the wheel hub assembly, once you pass a signal current (alternators work very similarly, except they have two sets of coils instead of a steel housing) through the windings it will magnetize the field coils and the rotation of the steel housing will generate electricity as the plates pass over the magnetic coils of the stator. All you need is wiring on the back of the hub to shuttle it back to the battery, and the motor doesn't have to get involved so that it can instead take a break (a brake?) and cool off while you're slowing down.
Um what? Brake-by-wire is becoming more and more common, especially on hybrids and EVs... they're coming whether you like it or not. Thankfully, current systems are a hybrid setup that have hydraulic redundancies, so you're not completely screwed when the electronics fail.
Trailer brakes are 100% electric, and in 8 years of working on them I’ve yet to see one fail due to an issue not related to lack of maintenance. An argument can be made that they’re a supplemental system, however you’re supposed to slow your truck with the trailer as the primary brake force, not the other way around. They work and they’ve been around in the current form (an electromagnet with a wear surface “shorts” to the drum causing the shoes to engage the drum) for literally ages.
Well I really think that breaks on truck and trailer are pneumatic. At least they were when I was driving a truck and that was yesterday. Or maybe it's an American thing to have electric truck brakes
@@klauskarlkraus I think he's talking about trailers with pickup trucks. I have yet to see a semi-trailer use electronic brakes, and I'd be freaked out if I saw them, considering how many electronic issues I see on many trailers. And that's with heavier gauge wire and connections. They still wear out and get corroded. Yea, the air brakes systems on trailers fail sometimes, too, but there is a failsafe where if pressure drops too low, it actuates a mechanical brake that stops it.
Those brakes work fine on a trailer because the delay and lack of modulation doesn’t really matter. Basically there’s not really a smooth way to engage them so they delay till slack it taken up and then apply. You can vary how hard they apply, but it isn’t nearly as sensitive as hydraulic brakes. And, I’ve seen plenty of electric trailer brakes fail. Wiring gets damaged. They get overheated. They get worn out. Springs fail and everything comes apart inside the drum. I guess you can blame everything on lack of maintenance, but failing is failing.
@@NBSV1 I only said they’re on the road, not that they’re perfect. :) Lack of maintenance or user error, always has been what I’ve seen. The same can be said about hydraulic systems as well.
Honestly i hate the drive by wire gas pedal in my car doesn’t always work the way I want it too or do what i want when trying to rev match . feel like brake by wire is a bad idea not a fan
Take a look into throttle controllers if you haven't, improved my drive by wire throttle feel and is adjustable. Helps a lot with rev matching in my vehicle too.
@@RGV2300 electric throttle bodies can actually be tuned to feel 'quicker' and more responsive than mechanical throttle bodies. Manufacturers just tune them differently for emissions. Go watch EngineeringExplained's video on it if you're interested, its pretty cool stuff - especially in the aftermarket where people aren't limited by emissions regulations.
Also, You know how most older cars have a parking brake in the form of a large lever instead of a button on some cars? That's not only to keep your car still when It's parked. It's also a last ditch emergency brakes, connected to your brakes directly by steel wire. Also another nice thing with manuals, you can downshift to PREEETTY high RPM's over what you usually use on a normal car and then use the handbrake to catch the last bit of braking.
On the other hand, modern e-brakes (I heard that it's not universal but german cars usually do it) are designed to bring a car safely to a stop (aka with ABS). Holding the e-brake will override pedal inputs so it will also work for the passenger if the driver falls unconscious.
Losing power in a car with power brakes is also terrifying. Not only can you really not brake, steering is also super difficult (power steering). This happened to my wife while descending a very long hill. She had to use the EMERGENCY brake to stop the car. Thank god that wasn't electric, but an old-fashioned cable/handle type.
@@justayoutuber1906 Really irks me that we'd make something that can be life saving worse just for some quality of life. It's not too common here in Europe, luckily. most cars I've been in here still have hand brakes. That is also what they're called in Swedish. We're quite literal.
Exactly what I thought too. Problem with this system was that it was kind of prone to electrical issues. And to people not going in to have it serviced when the system told them to. Which could lead to complete brake failure. So Mercedes discontinued it.
I had a mild wreck in an old manual gti thanks to a caliper coming off. Split my wheel in half, ripped caliper and rotor off the car, and sent me into a spin because of the initial wheel lock up. Still drove it home with no brakes lmao
Having lost breaks totally to a semi smart system twice I'd much rather keep old hydraulic breaking systems. Several reasons: One lose power possibly loss brakes. Two get a glitch in the smart system it can cause you to crash. Three if it's hooked up to the ota updates and not fully secured which nothing 100% is, it's yet another point of failure or vulnerability. Four if you lose power brakes may lock up in default like a truck or bus air brakes causing a crash. Hydraulic system has one failure point, lack of fluid. Everything else is a wearing part that periodically needs replacing. Electronic you add another half dozen potential failure points at minimum.
And, with smart brakes, you get the dumbshit BMW drivers who dust off your front bumper as they swoop in front of you. The truck auto brakes, unexpectedly - and you've got a Swift driver right on your back porch with questionable skills and brakes, himself.
A loss of power does not mean loss of braking. The Audi has a check valve that switches back to normal hydraulic braking if there's no power. A glitch is very unlikely. There are a lot of regulations in how electronic systems should be developed for cars that require redundancy and fail safes from simple stuff like using ECC memory to full self checking systems. There are already very proven electronic systems for other things, so brakes are not far off. The points of failure depend on how you count. Here you're counting loss of power, glitches and updates whilst saying the only point of failure for hydraulic is the fluid. You can also say that the master piston is a point of failure, the tube connections, the tubes themselves, the brake caliper piston, etc. The fourth point doesn't make sense, if you've watched the video you'd know that that isn't the case here. Also, the braking by default is actually considered a safety feature in trucks and busses because it prevents them from not being able to brake and running off. It's ironic how you are both afraid of an electronic system causing brakes to stop working and seeing brake as default as dangerous.
Personally, even if brakes become full electronic, they should still have a backup hydraulic system just in case. Its always better safe than sorry, and having backup systems would pretty much reduce any chances of brake failure to a minimum, unless of course, a dumbass decides to drive with worn brake pads.
yes and no, yes there are more components that are there to provide regenerative braking with a "hydraulic feel" and a more advanced "brake bias" but in the end when everything electric fails you can still just push the pedal somewhat deeper and benefit from the good old reliable hydraulics... the only thing left is that audi brake systems are notorious for sticking (in the brake position) when getting old. Probably the etron needs them to be rebuild even more often
I don’t know Rick, as you say electronics depend on there being power, good old hidraulics don’t have that problem. Yea, a hose can break, but so can wires
Not perfectly true. An Eddy current brake combined with a solenoid spring set e-brake would be a fully electric and self contained system that would be every bit as reliable, work at all speeds, and not need any external power beyond what would be generated by the motion of the car itself. It could be computer disengaged when not desired but itself would not need a computer. And because it would be made of solid state components, would not degrade with age like rubber hydrologic hoses can.
I so don’t trust electronic brakes! I don’t even trust drive by wire or auto parking. What happens if you’re doing 70 down the interstate and a glitch makes your car decide to parallel park? Death that’s what happens.
Oh Oh By the way Please mention the Gain in pressure from the mechanical levers specially on the rear of a motor cycle. Hydraulic rear breaking on Motor cycles Is a recent development. My Dumb ole 86 yamaha has fully mechanical rear brakes because it has Drums In fact Most if not all drum brakes on motorcycles are Mechanical . Hydraulic braking on production motor cycles didn't happen till the 750 honda which was the first disc brake on a motor cycle that i know of.. Oh dig Honda was the first Production bike to have hydraulic braking with its disk brake. In 65 MVAgusta introduced disk brakes to their racing motor cycles. Honda saw that and said we'll get them discs too. The rest is history . But still many motor cycles have drum brakes as well as motor scooters which just don't have room for discs. So Jerry Try to remember history it won't let you down. Also Honda engineers are the best !!!!! Yamaheha engineers are second best maybe. Cheers
There are two things on a car that, for comfort and reliability, should be mechanical and those are the brakes and steering. I think that even the steering locks when the engine isn’t running are a bad idea, had it happen once but the engine fired back up just before a turn.
Ok I honestly thought that locking the steering with non running engine is a myth, can't believe it isn't, not only is it dangerous it's incredibly stupid, and you'd think cars are designed by smart people! Then again fully mechanical steering means driving a car is a constant workout, but there are designs of electric or hydraulic steering which keep the car steerable even if the corresponding systems fail.
@@mihan2d power steering assists steering with hydraulic fluid, older cars also have this but the steering doesn't lock when the engine isn't running, it just becomes very hard to turn. The locking feature is there for anti theft and for parking on hills so your steering wheel can't center itself when rolling down the hill.
@@mitcheloo2632 Electric steering with planetary gears also allows to steer if the motor fails. The anti-theft and anti-rolling things work as an explanation but at least then they must have a sensor/electronic check in place that locks the steering ONLY if the car is stationary when the engine shut off, that's so easy to implement yet they didn't bother, putting people in danger...
"I think that even the steering locks when the engine isn’t running are a bad idea, had it happen once but the engine fired back up just before a turn." This isn't a thing in any of the many cars I've owned. Just don't turn the key to the off position while you're trying to steer. If you have to restart the car while moving don't turn the key off first. You might have to muscle the steering but it doesn't lock.
@Quade Masters Didn't turn the key off, had an engine fault here it would kill itself during driving (was a Volvo V70) never found the issue so we sold it (yes we did mention the issue, I’m not an asshole).
What's the point of electrifying brakes!? "it'S aN oLd sySTeM!" Yes, because it is a great system that has worked better than anything else we have come up with - like electric brakes - Which are just electric to fill the gimmick of being electric...
Maybe autonomous driving & automatic braking can still be used with hydraulic brakes, by adding another motor that pushes the master cylinder (without the driver having to press the brake pedal), with the motor activated by the car's computer whenever it decides it needs to automatically brake

The gen2 prius literally had an electronic braking system. It has a stroke senosr that simulates the feel of a conventional braking system. Low speed and emergency braking is the only time the hydraulic brakes operate. Thats why they don't need their first brake job until well over 100k miles with normal driving habits.
I like how the monster logo is the only one blurred of all the logos on the dirt bike lol
not sure what happened, but my friend's new Corolla just lost the brakes at a stop light, no crash, but he had to have it towed to Toyota and they had to replace $3,000 of the "brakes" under warranty of course, so even the old hydraulic brakes can fail on a new car.
Simple answer: they cant work if the ecu is broken lmao
All you need is a laptop in the passenger seat 🤓
Electronic foot brakes might not be very common but electronic handbrakes are becoming much more widespread. I definitely feel a lot safer with an old fashioned cable handbrake...
Every time you pass a car bq on the freeway.
Also current steering is hydraulic assisted steering. True hydraulic steering is only available off road as there are no pitman arm down mechanics.
BMW had that system in the R1150rt for a couple of years. It was a disgrace as it wasn't very fine tunable so many people would be dropping the motorcycles when trying to ride the rear brake.
My dad once parked at a place where some gangsters didn't like that he could see into their office. They cut the break wire, and my dad started to reverse into a bigass gap, now he's dead. Just kidding, he could stop with the handbrake, he died of colon cancer.
Actually we got electric brakes in 400 ton dump truck. But they are built to be safe. Basically there is huge ass spring applying brakes all the time and there is huge ass electric bit that prevent spring to apply brakes all the time so you can move.
Basically in order to drive you need electrical power in order to stop you need nothing, just remove power from electric bit and brakes are at full stopping power.
Not sure if that would be smart on 200km/h car but on slow dump truck is perfect
It's no worries if you lose power with electronic breaks! As Audi describes, if you lose power, a check valve means your electronically controlled breaks are now regular old hydraulic brakes, and your foot does all the work again. Phew! 😅 And, electronic brakes have the added benefit of being able to stop with the brake fluid boiling, as they can pressurize the "air" enough to stop the car, versus a brake pedal which just hits the floor, and then you're done. Neat!1!1
be honest Jason, you're buliding your own brakes.

I think I remember an F-22 test pilot giving a lecture and mentioning the new fighter jets had the control stick not move at all, it would sense the pressure the pilot exerted on it, and how it was really weird for the human pilots and they had to design sticks that moved.
I may be incorrect, but I think this was something first tried in the F-16, and since humans are better at knowing the position of our limbs than how much pressure we're exerting with them, they found it was more intuitive to build some movement back in to avoid feedback loops of pilots overcorrecting errors. I wonder if the f-22 control stick was identical!
My source is "The insane engineering of the F-16" by Real Engineering, around 22:30.
Current electronic brakes are just hydraulic brakes with extra steps
Extra steps equal more parts breaking
@@dafin7378 exactly
As the video said, there are several perks, and also:
1/ electric brakes can stop the car even if there's hydraulic failure, and redundancy is good for safety and reliability
2/ it can be controlled electronically that might be able to assist with self-driving
3/ regenerative braking can improve fuel economy
Regenerative braking is going to be really important in future as cars are becoming more and more efficient.

@@huleyn135 Nope, if the lines on the brake fail, your foot would feel like you're normally braking but on the tire side it'd be squirting fluids
I believe electric parking brakes have an emergency stop mode by holding the button. Consult your vehicle’s owner’s manual obviously
I'm 90% sure it's supposed to have the same function as the vacuum booster (electric motors have no vaccum) and make the pedal lighter
@@Justpassingb1 usually electric e brakes have an emergency mode when pulled at speed, and it brakes the car and even uses the abs data to not lock up
Just like everything that the Germans make over complicate a simple system
I like the title and the explanation of the basics. There's even more to it: In May 2004, Mercedes recalled 680,000 vehicles to fix their complex brake-by-wire system. Then, in March 2005, 1.3 million cars were recalled, partly because of further unspecified problems with the Sensotronic Brake Control system. If the electrical break failed, they had a classical foot driven hydraulik backup, but only to the front wheels and without the typical vacuum servo assistance. That happening without pre warning resulted in way longer brake distances, subsequently leading to some accidants of almost brand new, well maintained upper class cars. In 2006 they discontinued the system in the E- and S-class limousines.
Secondly: There were cars, that had no direct hydraulic connection from the break pedal Movement and no feedback at all: The Citroen DS and CX upper class cars had just a foot controlled, spring loaded hydraulic valve for breaking. A single belt driven pump provided hydraulic pressure for the breaks, the clutch, hydropneumatic suspension including the dampeners and for the power steering, that also had no mechanical connection to the steering gear (but a mechanical fallback with extremely wide dead clearance) . Buyers loved the lack of feedback, testers hated it. They sold 2.5 Million from 1955 to 1991, not so bad for upper class cars of legendary complexity and maintanance costs. If the pump failed, there were several storage tanks, that provided full usability for some more minutes. For example after 20 times of breaking, it stopped working and you were left alone with the mechanical handbreak with litereally coin sized brake pads (on the Citroen CX). The system worked surprisingly well, the safety record was flawless.

Regenerative braking can actually be done so well, that you hardly use the regular brakes at all. In fact, if you press the brake, it will also regen brake first.
One pedal driving is a common thing in EVs. You are just using the actual brake calipers when you have to brake more in unexpected situations, or you just driving faster, requiring more brake power to stop for the red light.
Agree to that. Regen braking (especially if you have front motor) can cover 99% of traffic situations. New trend for electric commuter cars is to reduce max speed anyway, so all that means that brake overheating will not be an issue. Ventilated disk will not be necessary, brake calipers and pads can be also made smaller and lighter. Additional bonus is the reduced unsprung weight...
Of course, with performance cars, it is another cup of coffee :-)
Same concept as driving an ATV or side by side with a CVT transmission, one pedal driving. Those cvts have very snappy engine braking ability
@@drazenradosevic7467 Normal size pads still needed for emergency situations, but you basically never need to change them since they are rarely used under normal driving. The Model S Plaid under full breaking from top speed to zero, even with regenerative braking to assist, the calipers get very hot. This is a bit of an extreme situation, but there is a need.
This is the answer of when electric brakes will be common on cars.
It will only happen after the majority of drivers are driving EVs with regenerative braking. Once people get used it, and get comfortable with regen braking, they'll be more receptive to fully electric system.
I put 6500 miles on my hybird & I thought something was wrong with my brakes. Come find out I never broke in the pads

Refilled oil, it runs again. The reason why this happens is bcoz my mother does not drive the car too often and only few kilometers at a time, i doubt that the oil ever reaches more than 50*C temp, this means, quite a lot of condensate water collects everywhere.

Especially when that electronic system would fail with every other electronic system on the car. The reason hydraulic brakes stick around is because their mechanical function is completely independent from the alternator.
there are some advantages actually. better automatic braking is one of those, but one thing that i wished they had mentioned was advantages in the event of brake fluid boiling. your brake pedal can only travel so far but an electronic pump can just keep pumping fluid until it moves enough fluid to stop the car. i watched one video on the c8 corvette where they talked about that. obviously, you can’t just keep driving with the fluid overheating, but it’s enough to stop the car in the event of such an emergency.

So many "innovations" in the auto-industry feel like fixing what ain't broke.
I mean, most innovations are just improvements on existing technology
It mostly exists because people aren't smart enough to know that one click on a hand, or pedal parking brake, isn't enough to stop a car from doing anything. 95% of the time when a customer has a traditional parking brake they just set it to where it barely contacts, it won't even stop the vehicle from moving under the pressure of the torque converter.
Exactly! Electric steering and Drive by wire (Accelerator) being the worst! Customer is no longer the king, it's profits and fickle minded customers who dictate what to manufacture. The car companies are having a gala time these days. Sad really.

The Citroën DS also had an assisted break with no feedback in the break-"button", people did get used to it.
Indeed… I had an SM, which had the same system. These cars had a high-pressure hydraulic pump that actually supplied the pressure. Your foot on the “mushroom” simply opened a valve. Yes, we got used to it, but these were by no means sports cars… It is the equivalent of a steering system that gives very little road feel. There was an accumulator in the system, so that you still had a pressure reserve in the event of the engine quitting on you… which the Maserati V6 had a anasty habit of doing, in very bad ways…
Also, any vehicle with air brakes will not give any feedback.

@@blakeyboychar Toyota still uses 20+ year old designs in their vehicles. That's why a Tacoma still has a handbrake, drum brakes, the same Bilstein shocks since the 90s, a transmission which came out in 2002, and an engine that's also from the early 2000s. Granted, those designs are slightly modified, but at the core they're still the same. Sure they have added a lot of electrical stuff to it as well, but mechanically, those vehicles are ancient. Even if the electrics fail, mechanically it'll keep working.
Especially Audi..... They always want to be the first to do something. This one ain't too great in my opinion.

Does that mean your work is paying to keep you from working technically
Brakes will always need a backup system. As in power brakes and power steering. Parts critical for the safety just need a working manual override. BTW, about no power situation: it's actually solvable. Think of the brakes that are "normally closed" and you need to actually provide power to lose them. The hard part is to make it energy efficient and fast at the same time.
So you're doing 75 mph on the interstate, the electronics for the brakes' take a dump and your brakes lock on......Yea great idea.
“The scariest thing is wanting to stop but not being able to.”
Yes! This has happened to me several time with my 2003 Ford E350! It has huge duel piston calipers at all four corners and requires an extra belt driven vacuum pump on the front of the engine to help the normal vacuum booster for the brakes. In my 18 years of ownership, Ive flown through a few stoplights and into some ditches when that stupid pump fails. Your butt seriously puckers!!!!

Switch to hydro boost
The reason hydraulics stick around is simple: When the engine fails, they still work. When the electrics fail, they still work. That's the point. And that's also the reason handbrakes have stuck around: Because a cable/rod driven handbrake is your last resort when hydraulics fail, and yes, I've had to use it in that situation.
Handbrakes are also know as E Brakes, Emergency Brakes :v
same i had problems of low brake fluid pressure in the brake lines before and had to rely on handbrake in those instances, so your explanation about the isolated forms of failsafes in these systems and not being codependent (if everything is electric and the battery dies then everything doesnt function) is important reminder as to the necessity of keeping the function of these different systems seperate and isolated from each other, Slam Shift with the best answer imo
handbrakes are being phased out by electronic parking brakes. most new cars have no mechanical fail safe for the service brakes.
@@c30mob7 worst part is you cant do a hand brake turn
Handbrakes/e-brakes should NEVER be used as an emergency brake.

I don't remember that. Can you clarify?
I've had first hand experience with brake loss when exiting 70mph interstate to 25mph off-ramp to a stop sign. So happy my e-brake worked.
As an autozone employee, we will have a printed code, we don't get payed enough for all that bull shit
That would be the first AutoZone I've ever seen to go that far into doing that, also she's a regular " Red " shirt CSR, why isn't the manager doing all the extra work seeing as they would be pissed if a red shirt took that much time with one customer and they had to come out the back and put down their phone to help other customers cause of that.
Also, if AZ ever seen this comment while your a current employee, you'd be getting a pink slip regardless if it was a negative or positive comment, and maybe even sued if they wanted to go that far, look at your Zoner Manual, the job isn't worth the BS anyways.
As a dealership advisor, it sure is fun when anyone comes in with a print out from AZ and says that they know what is wrong with their car because they got the codes. Takes a while to explain to them that the code gives you a place to start diagnosing, not always an exact fix from just the code.

I have a great idea for brakes, I’ll design a transmission that makes it so when you push the clutch you can put it into reverse so you have the power of the whole engine to stop you, I call it the transmission destroyer
Design? Isn't it already available?
Oh shit.. I think we need a new truck at work...
I fr thought I was about to hear a good idea 😂
clutch fryer too
I think this would be possible if your reverse gear had a synchroniser, but I’ve never heard of a car that does. Most cars don’t, hence why you have to stop fully before sticking it into reverse
@@th3airraidsir3n5 not at all, In autos you can slam that bitch in reverse going foward
The Nissan Leaf does this in an admirably simple way: the master cylinder is just set back about an inch and a half from the pedal arm, so the first 2 inches or so of pedal travel are just an input to the computer asking for regen braking, but if you push further, you hit the master cylinder and apply the friction brakes. so even with no power (12V and traction battery disconnected) you still have conventional braking to stop the car. The power steering works the same way, just with an electric pump instead of a belt driven one.
Thats why I like 90's and early 2000's cars the most, they have just the right balance between not being carbeurated but also not scull fucked with expensive shittly made electronics
I just picked up a 2000 Town Car Cartier, and its the perfect amount of luxury and comfort. No crazy computers and over complication, just simple cool features, like heated seats where you can choose to heat your back or your back and ass, 13 way seats, sun roof, etc etc
100%, even in the late 90s you can get EFI, OBD2, ABS, dual front side airbags, etc. depending on the car. Into the early 2000s some also had lane departure and auto braking. I think the modern era of tiny turbo-charged engines and luxury=electronics in particular is a downward spiral.

My car used to have in-car mariachi band but figured it'd save more fuel to leave them behind when I'm driving
I had my brake line burst on my Silverado coming up to a red light @ 50MPH. F'n terrifying. Was able to jump on the shoulder and pump what was left of the brakes before hitting intersection. So hydraulic isn't perfect either. For electronic brakes, you would absolutely need some form of fail-safe system like railway air brakes. So that if all power is cut, the brakes are applied. An example could be a spring powered clamping brake pad that's held open when there's power but clamps disk if power is lost. Would really suck having car suddenly stop by itself but way better that suddenly zero brakes, I can attest to that personally.
That's probably only from lack of maintenance though
Handbrake? Or is it 'E-brake' in US? Which I thought meant electronic, but means emergency in that case?
So now if your electronic brakes fail, you still have hydraulic, and if they fail, you have e-brake, and if that fails, you can engine brake shifting down, but maybe not if you're using automatic transmission. Simple....?
Sounds like damage or poor maintenance. That is no criticism of hydraulic brakes.

Under rated comment
I think electronic breaks should be designed in a similar manner to air breaks where breaks are automatically applied when power is lost. Though my preferred braking system is mechanical breaks.
that's how most are designed tho
So, if for some reason you end up with no energy in the middle of the road... How do you, you know, push the car to the side of the road, for safety reasons?
Like my grandfather use to say "If it ain't broke don't fix it"
I missed what the benefit was to having electric brakes in the first place was
More profit for Audi is the benefit.
I think the benefit is the computer can slow the car with regenerative braking so the brakes last longer and you get a slightly longer range. I’d rather do regenerative braking manually either with a separate lever or just sticking it in reverse while still pushing the throttle like with electric forklifts
@@lazarustheatv8389 re: "I think the benefit is the computer can slow the car with regenerative braking so the brakes last longer and you get a slightly longer range." not so much, that's for BEV's with an electric motor. in contrast the Corvette C8 is full ICE (for the moment at least) but indeed has the fancy "quasi electric" braking you're all talking about.
A conputer brakes better than majority of drivers and you can have sensors that automatically activate the brakes if it senses a collision.
JERRY!
I don't like what you said about regenerative brakes either! It's not driving the motor in reverse! You should really know that electric and hybrid cars still use transmissions, the motor is either on the other side of the transmission, or in the case of hybrids, between the engine and transmission. Regenerative braking works by building a generator into the wheel hub assembly, once you pass a signal current (alternators work very similarly, except they have two sets of coils instead of a steel housing) through the windings it will magnetize the field coils and the rotation of the steel housing will generate electricity as the plates pass over the magnetic coils of the stator. All you need is wiring on the back of the hub to shuttle it back to the battery, and the motor doesn't have to get involved so that it can instead take a break (a brake?) and cool off while you're slowing down.
I'm glad they haven't done drive-by-wire brakes, there's already plenty of tech I have to repair and diagnose.
I m u s t s n u g g l e t h e w o l f
th-cam.com/video/Vzbx492xRLY/w-d-xo.html
Um what? Brake-by-wire is becoming more and more common, especially on hybrids and EVs... they're coming whether you like it or not. Thankfully, current systems are a hybrid setup that have hydraulic redundancies, so you're not completely screwed when the electronics fail.
I don't trust anything that is electronically controlled especially brakes
Trailer brakes are 100% electric, and in 8 years of working on them I’ve yet to see one fail due to an issue not related to lack of maintenance. An argument can be made that they’re a supplemental system, however you’re supposed to slow your truck with the trailer as the primary brake force, not the other way around. They work and they’ve been around in the current form (an electromagnet with a wear surface “shorts” to the drum causing the shoes to engage the drum) for literally ages.
Well I really think that breaks on truck and trailer are pneumatic. At least they were when I was driving a truck and that was yesterday. Or maybe it's an American thing to have electric truck brakes
@@klauskarlkraus I think he's talking about trailers with pickup trucks. I have yet to see a semi-trailer use electronic brakes, and I'd be freaked out if I saw them, considering how many electronic issues I see on many trailers. And that's with heavier gauge wire and connections. They still wear out and get corroded. Yea, the air brakes systems on trailers fail sometimes, too, but there is a failsafe where if pressure drops too low, it actuates a mechanical brake that stops it.
Those brakes work fine on a trailer because the delay and lack of modulation doesn’t really matter. Basically there’s not really a smooth way to engage them so they delay till slack it taken up and then apply. You can vary how hard they apply, but it isn’t nearly as sensitive as hydraulic brakes.
And, I’ve seen plenty of electric trailer brakes fail. Wiring gets damaged. They get overheated. They get worn out. Springs fail and everything comes apart inside the drum. I guess you can blame everything on lack of maintenance, but failing is failing.
We have a PJ dump trailer and 1 of the 4 brakes didn’t work from factory. It’s only a 2015 and is used a handful of times a year…

@@RGV2300 electric throttle bodies can actually be tuned to feel 'quicker' and more responsive than mechanical throttle bodies. Manufacturers just tune them differently for emissions.

@@Thebadbeaver9 If you want a better throttle response get a n/a v8 and stop messing with electrical throtlle u will just kill the engine
Also, You know how most older cars have a parking brake in the form of a large lever instead of a button on some cars? That's not only to keep your car still when It's parked.
It's also a last ditch emergency brakes, connected to your brakes directly by steel wire.
Also another nice thing with manuals, you can downshift to PREEETTY high RPM's over what you usually use on a normal car and then use the handbrake to catch the last bit of braking.
Most important thing a handbrake is for: Drifting.
On the other hand, modern e-brakes (I heard that it's not universal but german cars usually do it) are designed to bring a car safely to a stop (aka with ABS). Holding the e-brake will override pedal inputs so it will also work for the passenger if the driver falls unconscious.
Losing power in a car with power brakes is also terrifying. Not only can you really not brake, steering is also super difficult (power steering). This happened to my wife while descending a very long hill. She had to use the EMERGENCY brake to stop the car. Thank god that wasn't electric, but an old-fashioned cable/handle type.

@@tannerlotito3313 how so?
Having lost breaks totally to a semi smart system twice I'd much rather keep old hydraulic breaking systems.
Several reasons:
One lose power possibly loss brakes.
Two get a glitch in the smart system it can cause you to crash.
Three if it's hooked up to the ota updates and not fully secured which nothing 100% is, it's yet another point of failure or vulnerability.
Four if you lose power brakes may lock up in default like a truck or bus air brakes causing a crash.
Hydraulic system has one failure point, lack of fluid. Everything else is a wearing part that periodically needs replacing.
Electronic you add another half dozen potential failure points at minimum.
And it would be entirely possible to have two independent braking systems, one for the front tires and one for the back
And, with smart brakes, you get the dumbshit BMW drivers who dust off your front bumper as they swoop in front of you. The truck auto brakes, unexpectedly - and you've got a Swift driver right on your back porch with questionable skills and brakes, himself.
Lol OK boomer
A loss of power does not mean loss of braking. The Audi has a check valve that switches back to normal hydraulic braking if there's no power. A glitch is very unlikely. There are a lot of regulations in how electronic systems should be developed for cars that require redundancy and fail safes from simple stuff like using ECC memory to full self checking systems. There are already very proven electronic systems for other things, so brakes are not far off. The points of failure depend on how you count. Here you're counting loss of power, glitches and updates whilst saying the only point of failure for hydraulic is the fluid. You can also say that the master piston is a point of failure, the tube connections, the tubes themselves, the brake caliper piston, etc.
The fourth point doesn't make sense, if you've watched the video you'd know that that isn't the case here. Also, the braking by default is actually considered a safety feature in trucks and busses because it prevents them from not being able to brake and running off. It's ironic how you are both afraid of an electronic system causing brakes to stop working and seeing brake as default as dangerous.
Personally, even if brakes become full electronic, they should still have a backup hydraulic system just in case. Its always better safe than sorry, and having backup systems would pretty much reduce any chances of brake failure to a minimum, unless of course, a dumbass decides to drive with worn brake pads.
That Audi's brakes are literally the same thing just with more components to go wrong. What's going to happen when that pump loses power?
yes and no, yes there are more components that are there to provide regenerative braking with a "hydraulic feel" and a more advanced "brake bias" but in the end when everything electric fails you can still just push the pedal somewhat deeper and benefit from the good old reliable hydraulics... the only thing left is that audi brake systems are notorious for sticking (in the brake position) when getting old. Probably the etron needs them to be rebuild even more often
I don’t know Rick, as you say electronics depend on there being power, good old hidraulics don’t have that problem. Yea, a hose can break, but so can wires
@@emerandu that's another big problem, electronics tend to be hard if not impossible to repair
Yeah but what if I drink all of the brake fluid? Shit don't work then now does it?
Can't drink electricity now can you?
Not perfectly true.
An Eddy current brake combined with a solenoid spring set e-brake would be a fully electric and self contained system that would be every bit as reliable, work at all speeds, and not need any external power beyond what would be generated by the motion of the car itself. It could be computer disengaged when not desired but itself would not need a computer. And because it would be made of solid state components, would not degrade with age like rubber hydrologic hoses can.
@@boggybolt6782 i think you'd have bigger problems than your brakes if you drink it you genius 😂😂😂
I so don’t trust electronic brakes! I don’t even trust drive by wire or auto parking. What happens if you’re doing 70 down the interstate and a glitch makes your car decide to parallel park? Death that’s what happens.

My Dumb ole 86 yamaha has fully mechanical rear brakes because it has Drums In fact Most if not all drum brakes on motorcycles are Mechanical . Hydraulic braking on production motor cycles didn't happen till the 750 honda which was the first disc brake on a motor cycle that i know of.. Oh dig Honda was the first Production bike to have hydraulic braking with its disk brake. In 65 MVAgusta introduced disk brakes to their racing motor cycles. Honda saw that and said we'll get them discs too. The rest is history . But still many motor cycles have drum brakes as well as motor scooters which just don't have room for discs. So Jerry Try to remember history it won't let you down. Also Honda engineers are the best !!!!! Yamaheha engineers are second best maybe. Cheers
There are two things on a car that, for comfort and reliability, should be mechanical and those are the brakes and steering. I think that even the steering locks when the engine isn’t running are a bad idea, had it happen once but the engine fired back up just before a turn.
Ok I honestly thought that locking the steering with non running engine is a myth, can't believe it isn't, not only is it dangerous it's incredibly stupid, and you'd think cars are designed by smart people! Then again fully mechanical steering means driving a car is a constant workout, but there are designs of electric or hydraulic steering which keep the car steerable even if the corresponding systems fail.
@@mihan2d power steering assists steering with hydraulic fluid, older cars also have this but the steering doesn't lock when the engine isn't running, it just becomes very hard to turn. The locking feature is there for anti theft and for parking on hills so your steering wheel can't center itself when rolling down the hill.
@@mitcheloo2632 Electric steering with planetary gears also allows to steer if the motor fails. The anti-theft and anti-rolling things work as an explanation but at least then they must have a sensor/electronic check in place that locks the steering ONLY if the car is stationary when the engine shut off, that's so easy to implement yet they didn't bother, putting people in danger...
"I think that even the steering locks when the engine isn’t running are a bad idea, had it happen once but the engine fired back up just before a turn."
This isn't a thing in any of the many cars I've owned. Just don't turn the key to the off position while you're trying to steer. If you have to restart the car while moving don't turn the key off first. You might have to muscle the steering but it doesn't lock.

Don’t ever get on a modern passenger airplane. Everything is fly-by-wire. (But of course they are quadruple redundant systems. )
Maybe autonomous driving & automatic braking can still be used with hydraulic brakes, by adding another motor that pushes the master cylinder (without the driver having to press the brake pedal), with the motor activated by the car's computer whenever it decides it needs to automatically brake
@@lzh4950 that really would not be hard to implement or bypass either.
