In all honesty death is not exactly a high occurrence.
“Speed has never killed anyone. Suddenly becoming stationary, that’s what gets you.” - Jeremy Clarkson
The norm is if someone falls they slide for what seems like forever within the track. This may be painful and create injuries but death isn’t to common. If you notice this guy died because of a high speed, hard hit which sent him off the track into a stationary object. A sort, of protection like tires at a race track, might have helped but we will never know.
It’s a rare occurrence but sad one never the less. That video will make many cringe and I know my girlfriend never wants to see that video again.
