- We've gotten way better at the engineering and design of road barriers - often in surprising ways - to dramatically reduce driving deaths.
To understand crash costs better, NPR has a great podcast on how life is valued: www.npr.org/2020/04/15/835571...

I launched two videos since with the same deep dive on how engineering has changed over time. One is on tires: th-cam.com/video/C9aX0vohM_8/w-d-xo.html and the other is on dental fillings and how they stay in your teeth th-cam.com/video/9o_8wT0k33M/w-d-xo.html If you enjoyed this video I think you'll like them.

Hey, you might actually see this if I respond to your recent comment. I want you to know that I am blocking your channel to remove this video from my recommended feed. I have selected “uninterested” at least 1,000 times over the past year but it is there all the time. I only post this because you may see this reflected in your analytics and not understand. I may not be the only one this has happened to. TH-cam is (probably accidentally) harassing me with your video. The only method provided to stop this is blocking your entire channel. Nothing personal or even professional so I thought it only fair to tell you. I’m not here to agrue, just inform. I have notifications shut off so I won’t even know if you respond.
Millions of hours of video but YT insists on pestering me with this 15 minutes.
No.
I am the opposite of the guy above me lolol. I'm so glad TH-cam suggested me your videos! I absolutely LOVE this style of video, and I appreciate how much work goes into each of these! you deserve so many more subs, heres +1.
Please continue to make this type of video. I enjoy watching them

engineers in the 70: Let's put jumps at the end of barriers, sounds fun.
we have the show Dukes of Hazzard to thank for that!
Nice grammar
I SAY JUMP
Hahaha
YEEEEEE HAAAAAW!!!!!
The whole time I'm watching this, I'm thinking, "Oof, if I hit a barrier, I wanna hit THAT one, not _that_ one."
Same XD
Still not hitting any of them is the best decision to make

I am entirely humbled a long line of people I'll never know have worked to secure my life and limb; we whinge about so many small ways we feel society fails us, but are unaware of the design, work, and policies that may have served us without our knowing. Thank you Andrew for a very educational video.
you are a good person
Every second a road is unable to be used = huge amounts of losses for logistics and industries so you're not what the government cares about.
@@edenassos if the governments in NA truly cared for your safety, the drivers license process would reflect that of countries with lower crash rates.
Whinge
@@edenassos The government may not care but citizens care abt each other. We try to make society better and safer
As a DoT worker I'd like to see you expand on the engineering of the truck mounted crash attenuators as well as their trailer mounted cousins. In my seven years of working on the roads I've been hit in crash trucks 3 times and have been on 8 different work crews that have been hit and in every instance everyone went home OK. Except the drunk guy that hit us at +85. He went to jail instead.
Keep up the awesome work.
When you said he went to jail somehow I breathed a sigh of relief. I imagine much worse. This also goes to show how safe modern vehicles are - being able to survive 85+ mph collision so that his ass can be put in jail.
yeah now as a DOT worker are you going out constantly repairing guardrails? because i see this one guy going around roasting you workers for not having them perfect all the time.
Wow, 85+mph? It's a blessing he didn't kill any of your crew. I just hope he'll never drive again in his life.
The thing I liked about Germany, when I was stationed there, is that if someone drives drunk or impaired and gets in an accident, they lose their driving privileges for life, which is the way it should be in the United States. No second chances for drunk, impaired, vehicle manslaughter, or even road rage.
@@jarrrr69 Steve eimers hasnt roasted my employer yet but i started a guardrail inspection program because of him

Those cable barriers saved mine and my kids' lives. I lost control of my car during and unexpected snow storm and hit one doing about 60. Totaled my car but we walked away shaken but mostly unscathed. I thank the stars for engineers, we wouldn't be here without them!
That’s a good ending, but I hope no one goes 60 mph in a snowstorm anymore
@@Avathreyn dude the fuck?
@@user-ut9ln4vd5m could also be 60 km/h which is about 37 mph
Judging by replies I’m sure this David fellow is just swell at parties.
In all actuality, it’s a relief no one was hurt in your situation. I have a higher appreciation for road barriers now thanks to both the video and this comment!
@@federicoalcantara4796 even 60km/h can be a lot in a snowstorm, especially if you don't have winter tires, or do have a driver who is inexperienced with driving in slippery snow. Heck, some rainstorms should slow you down way below that too.
As a guy that works for my states DOT I can say you put together a very informative video. I deal with all this on a daily basis and it’s great to see someone so well informed and educating the public.
I'm genuinely curious, so I'm sorry if this sounds rude, I just want to know more. Guardrail guy is a guy on TH-cam that makes videos of him walking around roads and showing every guardrail that's not installed correctly because his daughter was killed by an incorrectly installed guardrail. Is that actually an issue with the guardrails where if every bolt isn't put into the exact place it goes, can it actually kill someone? Because I feel like if that's true, wouldn't DOTs be making sure everyone knew how to install one before letting them go do it for real? Or wouldn't they have made some other regulation to prevent it?
I now pay more attention at the barriers around my city. This is knowledgeable and entertaining. Thank you Andrew!
Important note: 'phased out' means 'no longer approved for installation' not that they were all ripped out and replaced. Still plenty of older installations out there that aren't up to code anymore still spearing and slicing people.
Yeah I've definitely seen those types of barriers on the roads.
Correct. Its important to be able to spot the which is which, it might save your life.
Yep, I have a friend who got a piece of guardrail through her chin and jaw in an accident. Luckily lived with just a scar.
(Edit- and I'm not yet thirty, so this wasn't like ye olden times either)
@@barryallen5507 so you would know where you can crash safely? That's dumb, all crashes are accidents, you can't pick where nor into what you crash into, because it happens too fast to react 99% of the time.
@@Dragon_breeder all crashes are not accidents and it is often still possible to control the vehicle to a moderate degree during partial loss of control.
When I was 19, I hydroplaned on the highway at 70mph in a curve in the rain, the water was too deep because of welling and my tire tread was too thin because I young and broke, I was on a direct collision path with a Grove of trees that would have very likely resulted in my death, so I chose to actively counter steer (a tactic used in rally racing to control the forward direction of the vehicle moving at a high rate of speed on terrain with low traction) and allowed my vehicle to engine brake instead of using my brakes because that would have locked up my wheels and resulted in complete loss of control. I am alive today because of my ability to drive and the choices in made during that crash. Instead of veering off to the right of the road and continuing straight into the trees with only a seatbelt to 'save' me (more like kill me, check vehicle crash stats and impact of seatbelts during collisions over 40mph for context), I guided the vehicle back to the left leaning curve and hit the wire guard rail. Initial impact with the railing ripped my entire left front suspension out of the vehicle, causing my brakes to fail and leaving me with only one wheel to steer and a cable pull hand brake that controlled the rear wheels. I spun out and continued to redirect the vehicle towards the rail to the left side instead of the hill to the right side. I hit all four corners of the vehicle on the rail and did 2.5 full spins, after which point I had slowed down and dissipated enough energy that I managed to straighten out the vehicle even with one wheel and used my handbrake to stop just on the right edge of the road.
We're not all old or slow like you I guess. You can work on your reaction times through practice. If the only thing you know how to do in a car is travel in a straight line, you are certainly doomed in the event you lose control. There are advanced driving classes you can take to further expand your ability to mitigate danger in a loss of control event, like sliding on ice or hydroplaning or spinning out, I'd recommend you attend at least one.
The only way that you cannot pick where you crash is if you have total loss of traction (rare occurence), your vehicle systems fail due to damage (possible, but unlikely), or you are suffering from a medical emergency.
"That's dumb" personal experience and the entire racing industry begs to differ.
Restorable unit engineer's thinking process: "Just 5 more crashes and this baby will literally start saving us money!"
Omg guys, you better start crashing here or I’ll have to do it myself
It might sound weird, but you can always count on human stupidity. Crashes are going to keep happening, because idiots are given the wheel. This doesn't mean that everybody involved in an accident are idiots, no. What I mean is that in every crash, excluding some very specific circumstances like mechanical failure, an idiot is the cause.
@@PunakiviAddikti human error ≠ idiocy. every once in a while, everyone is bound to have a shitty day where they're gonna have trouble paying attention to the road but need to make a commute regardless.
@@yokowan I know, I understand human error. But I have seen and heard some genuine idiots behind the wheel. Think Karen T-bones another car because "she's too important to stop at a red light".
@@PunakiviAddikti those people exist but they're rare. I've run a fair share of red lights myself but never on purpose. it's unfair to say it's one in almost every crash
Thank you for posting this. im always worried about my family members dying in car crashes to the point of panic. You helped me a lot get over that by making this video. I didn't know this stuff.
Glad to hear! Helped me with my own anxiety too!
I'm a highway engineer with over 20 years of experience. Great job on this video. It has a lot of good information and explains MASH compliance well and why it's important. The historical progression of barriers also helps understand the topic and why it's so important. I've shared it with my group at work.

When this was posted on Reddit I immediately thought of you, lmao.
Henlo mark
This was truly and awesome educational video, even Mark approves!
This was so interesting and fun to watch. Ever time I’m driving I think of what would happen if I or someone crashed into a barrier. I’ve always thought that it would spear me, make me go airborne, or wondered if it will even stop me from going into oncoming traffic. Clearly after watching this video the technology and testing involved is way more vigorous than I ever thought. Great video!
This was surprisingly way more informative and enjoyable than I thought. Kudos to you, Andrew. Keep up the good work!
"with enough crashes, restorable units save money"
YO! We need some moah crashes ovah heah! Joey, go hit dat barrier a few times.

While safety measures have increased survivability of accidents, the root cause of accidents have spread unchecked in recent yrs.
In Ca, Latino drivers cause a disproportionate % of DUIs, hit and runs, distracted driving. Disregard for common decency, the safety of other motorists; and, even traffic law, run rampantly amok among Calif Latinos.
It'd be great if you could help shed some light on this censored topic to prompt proper public discourse and overdue action to address this taboo issue.
"head slap" sounds so innocent for instant death.
I vote we change it to "head splat"
*Slaps top of head

I never knew learning about road barriers could be so interesting
ikr
Always good to be reminded of the constant drive for improvement that happens behind the scenes
My dad used to work for the state back in the 80’s. He said roadworkers got busted…sometimes, after an accident damaged a guardrail, if the machinery was tied up…the guys would just use older cull post to reattach to guardrail. These post were barely in the ground a few inches and were basically just cosmetic.
I never knew this much thought was put into designing guard rails. Mind: blown
this much thought is put into toilet paper.
@@Tycy2014
You too ? Some times I can't remember which hand to use either.
Nasa has a 60 page guide on how to splice 2 wires together.
I once saw them installing them and they were using this massive piledriver to put the uprights into the ground. Those upright supports go so deep it's amazing. Here where I live they have tried to extend protection to ground level to protect motorcyclists as the upright can tear a human practically in half if hit the right way by a sliding human.
im a layman so how bout a net
This is the kind of educational content that should be on T.V.
No drama. No annoying dramatic music. No exaggerative narrators. No over-the-top CGI.
Just a very well-put together video that succeeds in making the topic guardrails really interesting! Very cool video!
what if i wanna watch dramatic music, and CGI
I don’t think this is true. I believe education shows on cable television should appeal to a wider audience who maybe are not as scientifically inclined than people who who would watch a 15:00 minute TH-cam video about guard rails.
Cool learning about things I see every day on the commute. I had a general idea of their purpose but now I feel I have a better understanding of why they were chosen over all the other options.
Yay yet another awesome free educator on youtube! I love you folks and what you do, thank you deeply.

I had no idea the “wasted” land between and beside highway roads was called a clear zone or that it’s specifically designed to save drivers. I just assumed it was “extra land” in case they decided to add another lane at another time.
Yeah, lol. I just thought it was land to separate the lanes.
If you've ever driven in an area where a snowstorm is happening, you're likely to see at least a few cars that have slid into those clear zones.
@@featheryfemme Which is called a clear zone. An area to separate the lanes. For safety reasons and so on 😉
It probably is. In the UK the hard shoulder where you can stop if you breakdown. Now in the Wisdom of some highway agency it is being gradually converted to an extra lane. Now it's breakdowns that are killing people...
I assume in many cases it’s a combination of both, with the median being in some cases wide enough to add another lane or two with a safe clear zone, or in others with an eye towards replacing the earthen median with a fixed (probably concrete) barrier, depending upon predictions of future traffic.
This is high quality content on whole other level, please keep up the good work.
I seriously show this video to people as an example of a subject I never thought would be interesting but is here.
It’s said that teacher makes a subject fun to learn or not, so you’ve done an excellent job on this.
I remember in college, in our first actual engineering course, they had us do some problems about this exact topic to drive home how deadly serious engineering can be, and the hard decisions engineers sometimes have to make. If you're making the decision whether to install guardrails, you don't have infinite money. If we want to make calculated informed decisions about where and when to install guardrails, you will eventually need to solve for x, where x is the value of a human life. As much as we'd like to think a human life is infinitely valuable, that would make it impossible to determine when and where to spend on safety improvements instead of, say, improving the roads, providing public libraries, or delivering mail. So there must be a number. Who decides x? Hopefully it's never me.
Read this just Andrew showed the table that included the estimated monetary value of a life
I remember in the 80's, I was probably around 8 yrs old at the time, meeting a guy that had part of a wooden (I believe) guard rail stuck inside of him from a car wreck that they couldn't remove for fear it would kill him.
I’ll do it
A doctor makes a mistake, one person dies. An engineer makes a mistake, potentially hundreds or thousands will die.
If we can say the Carnage Alley barriers were only installed due to the media exposure and lobbying, think that that same money could maybe have been used to make barriers in busier areas where it would save more lives overall.
Cable barriers look like they're designed to shred motorcyclists.
Looking at all the barriers, I dont think a motorcyclist would do well hitting any of them
@@ValentineC137 I would much rather hit a concrete barrier at a low angle than cables. At a high angle you're fucked either way.
@@lucaprinselaar Yea I think my odds of Evel Knieveling up the side of a concrete barrier are better than my odds of coming out in one piece with a cable barrier. I was in an accident and hit a car that was making an illegal left in front of me once while I was going like 85kmph and came out with no broken bones so not really much difference between that and hitting concrete really.
When a motorcyclists hits a cable barrier whatever side the ambulance is determines which bits get picked up first, cable barriers may be cheap but they are very dangerous to motorcyclists.
I’ve never seen them in Europe, so I think they might not be as good as concrete or guard rails.
This video is really excellent, every time I see a concrete barrier for the past two years, I think of this. Truly a fascinating look at something that blends into the backround.
Excellent video Andrew! Thank you for the knowledge sir, it, like it lives is priceless.
This was so cool. My dad was an engineer working on crash barriers in the 80's and 90's, and I went to a few crash tests as a kid. Unfortunately he passed away in the late 90's, so I never got to see his work as an adult, but then when you showed the first collapsible barrier I went "Hey, that's Dad's company's logo!" He's got several patents from '86-'98 on things like changing from the rigid guardrail ends to collapsible ends, as well as the crash barrels you showed. It was really cool to see the kinds of things he was instrumental in changing!
A collapsible barrier stopped me and my family from going off the edge off a cliff after we had hydroplaned at 50mph in heavy rain. It slowed us down enough that my dad was able to get control again and steer us back to the shoulder. Your dad's work saved us and will save many more lives to come. I'll give my thx to you so you can give it to him one day, if you believe in that. So thank you!
@@freddywesly If anything your dad's driving nearly killed you. Driving that fast in heavy rain near a cliff sounds really reckless.
@@cyan_oxy6734 not really. 50 is incredibly slow here in California for our freeways, and we were in the slow lane still getting honked at. Almost every freeway here is next to a sharp drop at some point. We just hit an unlucky patch of water going around a bend and hydroplaned. Even going 25 in a school zone, you can hydroplane. There's nothing you can do but wait it out
@@cyan_oxy6734
Yeah rolling over puddles at highway speeds while turning will surely make you hydroplane. Especially in the US where everyone's going almost 1.5 times the speed limit, especially in inclement weather.

Guardrails are one of those things that I drive by everyday and, see the changes and often wonder how exactly do they work.
I drove a wrecker for about 5 years in the mid-2000s, saw a lot of accidents with injuries due to the older guardrails. I saw how those work first hand while trying to get vehicles off of them and just wondered how this newer technology works. Thank you

I'm suddenly remembering something I think I learned in driver ed circa 1983, to the effect of guard rails are deadly. They're there to protect the road and other traffic from the crash, not the people in the crashed vehicle. I hadn't explicitly thought about that since high school, but I shouldn't be surprised to learn that engineers have worked on them and gotten better and better over the course of time.
Lmfao so basically they said "Sounds like a you problem if you hit a guard rail"
So basically it was "don't be stupid and drive responsibly", to the now "some people are too stupid and can't be trusted to drive responsibly, we engineers need to invent stuff to save them".

I had no clue there was so much engineering into a "jersey barrier".. Man such a cool video..
I thought Jersey's were concrete and metal was a guard rail
Right? Very cool engineering! Now we should put those wise minds to work discovering better ways to get energy without hurting the earth. And ways of being more efficient. Doing more with less and also reusing and not wasting things. 🌿👍✅
A well engineered guardrail saved my life when I got into a crash last year. Long story short I spun out briefly and slammed into the guardrail at 65-55mph and the airbags were broken on my old 2003 Taurus. I strongly believe the only reason I got through with legit just a few bruises and a very minor concussion+very very mild whiplash was a combo between my heavier car, the fact I didn't tense up, the modern guardrail, my properly adjusted headrest, and a newer seatbelt designed to slow you down slightly slower
Yeah I drove into a guardrail with a catchment net over the top, that net bounced my SUV back onto the road and had almost no damage to the car body
@@Selmarya I can’t tell if your trolling or not it’s funny imagining it in my head
i think the not tensing up during an accident is a myth other than that glad youre ok
@@sirepauly im actually pretty sure its true, that's usually why drunk drivers usually survive crashes, because the alcohol slows their reaction time and relaxes their muscles
@@sirepauly it's true, I'm studying physics and we learn about stuff like this, softer surfaces slow down the impulse (how long you hit the surface for) and tensing muscles makes your arms stiffer which means if they hit something they are more likely to break instead of bruising only

Thanks! I just realized hip hop explainer channels were a thing. Awesome stuff!
@@Lam First time coming to this amazing channel and is already so interested-!! Also very informative-!!
Seems like all those 80s action movies where cars are flying through the air aren't unrealistic.
Action movies not realistic? It JUST CAN'T BE!!
bruh haha
Just like a car's gas tank doesn't explode when struck with a bullet. Or a lot of bullets. Or at all. Practically never.
Like you can't break down an outside door with your shoulder or a kick.
About the only thing realistic about action movies is how often people shooting at one another MISS.
I used to get frustrated with how many bullets were wasted in action scenes (I still do). Then I learned that four New York City police officers had fired 41 bullets at the innocent and unarmed migrant Amadou Diallo in 1999, striking him just SEVEN times!
This is why I choose a shotgun for home defense. Preferably one with at least a 24-round capacity. Accuracy Not Required.
@@terrifictomm I agree with all your points, except the door one. You can kick down a door, just not with one swift kick, it takes multiple strong kicks
@@Calebnelson24
Perhaps. It depends on the the quality of the door.
Seriously though. What's with emptying your handgun at hiding suspects in five seconds when they aren't even showing themselves?
At least they don't throw their empty gun away anymore, like the used to in 50s and 60s westerns. That didn't make sense to me as a seven year old.
Good video, I wish there were more road safety videos available. You did a thorough job on this one. 👍
A few days ago One of those guard rails that collapses to the side saved my life on the highway. Thank u to the people designed and installed them.
I love how much engineering and research goes into these safety instruments. I assumed that highway barriers were there to protect against head-on collisions from accidental lane divergence. I didn't realize how much engineering went into the shape of the barrier in order to help dissipate impact forces, and kinetic energy; and to help contain rollovers, and vertical movement.
But still the usa has the most dangerous roads of all western countries..!
@@jacks3395 when trying to determine the most "dangerous roads" of countries there must be a lot of factors, not just guard rails and crash barriers. Number of vehicles, the weight of average vehicles, the expertise of drivers, age of drivers, the healthiness of drivers, length of roads, and location of roads (roads that go across mountainsides are more dangerous than highways due to the height and geographical factors), safety regulations, etc.
@@Marshark50 Wisconsin for example has a ton of drunk drivers because we're a generally drunk state.
@@jacks3395 Some say stroads play a role
As an Ironworker working on barrier rail on the interstate for miles at a time. A lot of work goes into keeping people safer on the road. It takes over 2 days just to put in the rebar to get a 150 ft stretch that traffic blows past in 1.2 seconds.Then it has to be formed and poured and stripped and polished… construction takes forever..
this was a REALLY cool video, I'm glad you made it. I've always been interested in how crazy effective those cable barriers were when they were new. it's cool to have all this crash safety research served up to me like this. and I only just noticed this seems to be your entry into this style of video? holy crap what an intro, I really thought you were just another one of those 10 million subscriber info channels.
Thanks a bunch! To produce this video took a ton of research, building new skills, the belief I could do it plus an amazing community of people who gave me incredibly great feedback to get it to this point.
It was so terrible and it took painful revision after revision to get it to this point. Even now I recognize there's so much more I could do but I just had to put it out to the world and see what the reaction was.
@@Lam Know that your work is much appreciated. Thanks!
If everyone learned to accelerated reverse bhop everywhere rather than using cars it'd lead to much safer roads...
DeSinc just wants to know which crumple zone would be best when he slams into it from a reverse accelerated bhop.
Since its your intro and thus a chance to learn --
I REALLY wanted to read the deaths per (something) per year but could not make it out. Deaths per million people, so 25,000 deaths in 1920? Or deaths per million cars? The new MASH guardrails image had type that was worse. Finally (I'm going to stop complaining after this one and just watch) the next was "...this compares two studies ..." which was ENTIRELY illegible. Why bother? Why frustrate us?
One of my petty persistent complaint with YT is that the text is often too small to read ... unless I lean forward and peer, or pull the screen closer. I'm not even counting the number of times I've tried enlarging the screen.
I tried googling: type script size per screen size
but I didn't understand the results. Maybe you will. If you must use small print maybe you should read it aloud as well. "This chart show ..."
Thanks for a good video.
Oh. Recently a woman was subject to a PIT maneuver and her car rolled over.
www.khou.com/article/news/nation-world/pregnant-woman-car-flipped-pit-maneuver-arkansas/91-0f48c495-f124-44bb-af4e-437014f5a97f
The police officer who had his lights on was trying to pull her over for speeding. She slowed and put her hazards lights on, looking for a safe place to pull over. He wasn't happy and used a PIT.
The road was under construction and had barriers on both sides, I think they were what you call "F" shapes.
The officer thought she should have stopped anyhow.
Maybe there should be signs up saying "No room for shoulder stop." to make it clear to everyone.
Now she's suing the officer and the force. Oh, and Arkansas police killed 3 people this year so far using PIT.
I regularly watch videos from Ron Pratt (Midwest Truck, Scott City Missouri). As a towing and recovery operator, cable systems cause him a lot of problems and safety issues when attempting to recover vehicles entangled in them. There is one of his videos where I guy was trapped in his car and Ronn had to lift the cable under tension with a rotator tow truck so that the man could be rescued.
Fantastic video. Well researched, understandably explained, professionally produced. Chef's kiss to you sir
"Multi car pileup in North Texas has killed at least 6 people."
"Incredible!"
Yea i noticed it aswell hahaha
Didn't know traffic in north Texas moved that fast. It would never happen in Houston.
@@perniciouspete4986 yep, I live in the DFW area where that happened and people speed excessively. The speed limit on the I-35 where that happened is 75 mph, but most people are going 10-15 over usually. Recordings from before the pileup show many of the vehicles were going ~75, even though we were in the middle of the worst winter storm Texas has had in a long time and roads were covered in ice. The sad result is a pileup involving 130+ vehicles and the loss of 6 lives. Even after that people still speed here :(
Funneling in with no where to go. Thank God for the lack of fire...
@Trevor W connotation dude, connotation.
Love how people are constantly innovating to save lives. As a side note, people often get upset when people in government say some life saving measures aren't cost effective but money is a finite resource and putting a bunch of it to protect against less likely hazards inevitably means stripping it from protecting against more likely hazards. It sounds callous but if your job is to save everyone you can with the budget you're alloted then you have to make sacrifices to get the most safety for your dollar.
I dont think it sounds callous at all, I think the people pretending their is an infinite resource available when there isnt are the callous ones, they happily sacrifice lives through ignorance of their own choosing. Being willing to stand up and say no when you know it will cost more lives to say yes is a brave act.
I wonder what would happen if we applied these same values to military spending, Medicare or education.
@@abiku2923 the world would probably be way more advanced tech wise. "The future is now old man"😂
There is a saying. Like it or not you can't save everyone. That's just the world we live in. Accept it and move on.
PS: dont even think about "I refuse to accept that!!!" Bullshit. This isn't an anime show.
Neanderthal Tom Cave Beast Sociopathic Parasite -
cut the military budget in half and using that money you could get ALL of the roads, in the US, covered in concrete barriers in 2 years. that's not a exaggeration either. people don't understand just how WASTEFUL our budget is and that in fact money isn't really a ISSUE.
that's just the federal government, local government isn't much better. all kinds of wasteful spending going on.
really the issue isn't money, it's who lobbies the government more that is the issue and who ends up getting public funds.
YES! Please do more of this type of content. Dash cam reviews are a dime a dozen. THIS is interesting!
In the 70s, I and my childhood friends were traveling with my dad on his work runs. We were in the bed of a camper shelled truck, when we were forced into a steel pole by another driver. The truck centered on the pole at the front bumper at about 30mph. Note, this is before seatbelt usage. Kids in the back were slammed into the back of the cab and the driver was propelled into the steering wheel. No major injuries. Why? We had hit one of the newly installed break-away poles that absorbed the impact and still kept us from careening over the overpass into freeway traffic. Roadway engineers are the silent protectors of us all!
Excellent Post on Guardrails with historical addition & updates. Thanks.
"has killed at least 6 people.." "incredible!" lmaoo wuuutt
Incredible 😃
🎉🎉*N-N-N-NEW HIGH SCORE!!!*🎉🎉

@@SofaMuncher I mean his tone especially was very jolly considering the situation. it was funny tho lol idk
@@zanechristiansen yeah i agree man it cracked me up
I really appreciate how you took the time to find examples of these systems in the wild instead of just using clips.
Very informative. I love learning how things work and you do an AMAZING job at explaining things.
Andrew, thanks for the great video. It really helps me understand the concept while preparing my PE exam
Great video! Should definitely make more videos like this!
I know that magpie from a mile away
i did a thing make a rocket powered road legal car and make it drive into a concrete barrier at 350mph
oh god...
you should make a vid of making your own(more effective) crash barriers

Ive always wanted to be an automotive engineer and your videos help with that. Thank you.
what a fascinating video, thank you for sharing! I find it really interesting how safety is handled for different parts of society. Like in aviation, a single fatal incident can completely transform the industry, whereas with cars it's assumed that people are gonna die, and it's more about reducing fatality than eliminating it. It's too bad so much vehicle safety is focused on the occupants though while pedestrians and cyclists are completely overlooked. A few years ago I was in the passenger side of my friends car on the highway when a drunk guy crashed his suv into us. I thought we were dead but fortunately we made it, maybe due to improved highway safety features, so that's a relief :)
Spent most of my life building highways so it’s kind of nice understanding the specific reasons for the different systems I have been seeing for a couple of decades. Plus you kind of explained the reason for the costly studies the often do before even beginning a project in the first place when you see all the things that need to be considered. Road work in general is not as simple as one would think. Fascinating really. I appreciate your efforts.
What kind of TH-cam name is that.
Sounds super insecure
I respect you for making that your username. Very bold of you.
Get me an internship, im a civil engineering student
lng name, why not just take: common a'hole ?
Really interesting - however the cable barriers are hated by motorcycle riders as the cables can literally slice limbs off. Suggest a follow up covering impact on motorcycles and the crash barriers.
And also low cars, especially convertables
In Europe they call cable barriers meat grinders for that reason. Great for cars. Killers for bikers.
He even mentioned the cost lol. Civilians are not gonna buy those things.
@@fynkozari9271 Civilians are not the only people that have to worry about cost, transportation departments do not have unlimited funding. Cheaper barriers means more currently unprotected roads can receive some protection.
Just dont drive a motorcycle. Lol. If motorcyclists cared about safety, they wouldnt be riding motorcycles. Just look at the stats. The stats for motorcycle accidents really makes me question their street legality. You literally just asking to die driving one of those things. And those guard rails ain't gonna do shite when the rider gets propelled off their bike and slams their head into the ground at 70mph.
this is fascinating! thank you for dare I say a crash course in just 15 min - very well put together video!

I literally have no idea who you are but i agree
ok
This was much more interesting than I thought it would be, now I'm going to be checking out barriers every where I travel
You test them too?
FABULOUS WORK 👏 THANK YOU ANDREW 🥰
Your channel is very informative dense. Thanks for creating TH-cam videos.❤
I remember when they changed the structure of road side electric and phone poles so that the pole gave way at the base to prevent a total car crushing. That was a major game changer in highway fatalities.
I used this to write an essay on road barriers in school. It was perfect.
Haha, thanks, I chuckled at the thought. It's good information so I hope you do well
By any chance can you share that essay here I’m curious to see it
I feel so lucky to be alive in a time that I can learn about so many interesting subjects so easily.
