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.
