    Racing is amazing when at high-speeds - but it comes with inherent dangers. A component failure, bad weather, or driver error can send a car flying towards the barrier at insane speeds.
    In my racing career, I had a crash at well over 100mph, so I want to explain what it felt like to hit a barrier like this and how technology has helped save drivers’ lives.

    Barrier technology has come a long way since the beginning of F1, back then they had very little protection for the drivers - often only using a few hay bales dotted around the circuit.
    However, as technology has progressed, more and more advanced barriers have been used to protect both the drivers and the spectators.
    For a driver, it’s not the speed that does the damage - it’s the sudden stop when they hit something. So it’s about acceleration, and the barrier's job is to keep this as low as possible whilst protecting the marshals and spectators behind them.
    Acceleration is the change in speed, divided by the time taken to slow down. A equals v - u over t. We often use the units of G for this, if you jump out of a plane - that sudden acceleration is one ‘g’.
    However, when hitting something in an F1 car, you can go from over 100mph to zero in less than a tenth of a second - this creates massive acceleration. And, the larger the acceleration, the larger the force that is placed on a driver's body.
    The barriers work by three main mechanisms to reduce this acceleration - Deflection, Deformation, and Momentum.

      1. Huracan Media

        There is no "genius" behind the F1 barriers, they partnered with the company that originally developed them for Nascar several years before F1 even thought about using them-sorry but Nascar track safety is lights years ahead on F1-One only needs to look at Romans nasty wreck in 2020 as proof. No Nascar track has steel barriers like bahrain, nascar eliminated those kinds of barriers in 2003-2005 for all tracks so F1 is only 15 years behind!

        ​@Smithy of 98 Deceleration is often misused as a term for slowing down. Technically speaking, deceleration doesn't exist and it's a made up word. You can experience a negative amount of acceleration, which is what people refer to as "deceleration". Because acceleration refers to the change of velocity of an object, it applies to objects speeding up and slowing down.

      3. Smithy of 98

        It's deceleration not acceleration

      4. American Pride

        Great video. Video idea: the thought process behind safety in racing, and how it has evolved over time. There are a million videos on the lack of safety, but there has never been an explanation as to why they thought that was enough, or too much, and how spectators felt about safety

      5. flynbenny

        The SAFER barrier has always fascinated me. A circuit I run at frequently was dropped from NASCAR and Indycar right when the SAFER barrier was mandated by those series (circa 2005), so it never got them. Those concrete walls around the oval and portions of the infield road course look kind of hard... Also a happy Nord VPN customer.

    2. SİCKBOY

      Can't believe I missed this Segway. Good job dude.

    3. Güllich

      it's actually not acceleration that is linked to passenger comfort but jerk, that is the derivative lf acceleration. all your explanations still apply but their goal is to decrease jerk to a minimum during a crash, not acceleration (well it does because it's a consequence but you get it)

    4. salim salim

      Too much talking

    5. Finn Creery

      Why don’t they put a 10metre foam wall instead of tyre walls

    6. hwd71

      Why don't they have parachutes?

    7. Sean

      Deceleration deceleration deceleration deceleration

    8. Roscoe Von gwipperton

      i think you mean deceleration

      I love your content, though I've read a story about NordVPN that really makes me not want to use their service - they had a security breach at their servers, meaning user data could have been stolen by a third party. They told no one. This was going on for 6 months before some whistleblowers started publicizing the issue and only then NordVPN has informed their clients about the security breach. They should have done that immediately to let them know that their data might have been stolen. They tried to sweep this under a rug and have demolished their reputation because of that behaviour. They have proven they are not about actual security but only perceived security. Unfortunately many VPN services do work like that and they oversell their services claiming that they provide security of technically impossible levels. Avpn service is not a magic bullet. It's a data funnel and if you can't trust the funnel operator like NordVPN - it's even worse than not using a VPN at all...

      Fascinating how much brain power we use to keep a hand full of professional drivers on an enclosed circut safe and how little we use to keep millions of sleepy amateurs safe, when they drive to work in the morning... "Lets plant an alley of trees 1 yard away from the road, every 25 yards, on both sides! What great idea! And even better, let us make the side of the road simply with dirt, so it gets gradually washed away until it can trap car tires, ripping them open, or flinging the car against the tree on the other side of the road! Sometimes my genius is frightening..." Idiots... Street planners could learn a lot from this video. Instead people defend them with" If everyone would drive perfectly, nothing would happen" Again... Idiots... If you look at the efford to keep professionals safe, in case they lose control, this arguments becomes a joke... Why do we learn from racecars regarding car safety, but completely refuse to learn about street safety? I can't really understand it.

    17. tribbinvw

      When you jump out of a plane, you experience 0G vertically (not 1G). At terminal velocity you experience 1G vertically, as if you were standing on the ground.

    18. Heretic123456

      Isnt it technically it's deceleration?

    21. Acias

      TecPro barriers seem like a middle ground between permanent SAFER barriers and tyre walls. I've heard that installing SAFER barriers at NASCAR tracks is a fairly expensive things and it seems you can't just put them on a street course easily. While TecPro do take more space the placement resembles those of SAFER barriers. Only problem seems that if you brush them a bit too much it might damage the car more than needed.

    22. Cantere Gonda

      I think it's Deceleration when u hit the barrier. Not acceleration.

    55. Flowers In Athens

      Rally barriers are the best

    56. paolo corti

      Could bushes or small trees be an option for runoff areas? I think it could really work because little trees and bushes need a certain amount of force to break, and that force is just perfect to slowly reduce the speed of the vehicle. The only problem I thought about is a fire risk, but a healthy plant has enough water in them augmenting the time necessary for ignition. I guess there is a problem that I did not think about...

    64. Klappspaten

      Not to be picky or anything, but jumping out of an airplane you experience 0g. You're in free fall. Standing on earth you're in an inertial reference frame, meaning objects without an acting force accelerate in reference to you. It's you standing still (or earths surface) who is accelerating, not the one who jumps out of an airplane. Magic of Einstein's Relativity

    65. Ibrahim Abas

      melboooorne ;P

    66. barillius

      1:03 .... Aceleration? Odd way to spell ACCELERATION. Also, the opposite of ACCELERATION is DECELERATION, not ACCELERATION. Hope that helps.

    67. The Transporter

      They don't call the Glen "the Widowmaker" for nothing.

      It's not about speed... Ok but cars doing 10mph don't flip 13 times either.

      Hi! Very interesting. I noticed at 4:11 there is water in the tyres. How does this affect the barrier performance?tia

    84. Brian Hiles

      (5:20) _Polyethylene_ tire tubes, not polystyrene. Polystyrene would shatter into sharp fragments, absorbing little momentum, as well as creating much detritus for the crashed driver as well as littering the track for subsequent drivers.

    89. Sawta

      It's fascinating to hear about the gravel traps and how they work. There are these things called Emergency Escape Ramps ( ) that I've seen posted on extremely steep mountainsides. The ramps themselves are long, but not _that_ long, and I often wondered how effective they would actually be at stopping an out of control 18 wheel truck if it lost its brakes. It's good to know that there's actually a very good chance it would be effective, if not outright safe to use.

    90. Melchor Vincent Agot

      Why didn't he talk about the tyres containing water and that those tyres were recycled for the job after being pulled out of road cars?

    91. Martin McQuaid "If you jump out of a plane, the sudden acceleration is 1G." Utter nonsense. I'm experiencing 1G sat here on my chair arguing on the internet.
