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.

      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.

    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...

    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

    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.

      @CloseCombat Clan Deceleration = slowing down, acceleration = change of velocity. But this definition of acceleration is more scientific, for everyday use people understand that acceleration is speeding up and deceleration slowing down.

      Acceleration is a change in velocity, when a car hits a wall its velocity changes therefore it accelerates. Acceleration doesnt only mean speeding up, in fact turning is also acceleration as you are changing you speed in a different direction.

    The foam in SAFER barriers is usually pink foam insulation boards. Cheap and effective. When light cars like INDYCAR runs at a track with them that was designed for NASCAR, every other foam segment is removed to make the wall "softer" because the light weight cars don't weigh enough to properly compact the foam the way a NASCAR or sportscar/endurance car would.

    My awesome idea that they are apparently unable to think of: Instead of gravel use fibers like an artificial hay field. Wouldn't be possible to skid across so it would always work, even if there's a brake failure. Also wouldn't allow for corner cutting like it is standard at present. Also the Safer barrier could be further enhanced with overlapping steel panels and a much wider space for it to move.
