Wow, that's a really excellent, though very scary, depiction of how much stuff actually happens in the 15-20 seconds of an accident.A few things that struck me.1- arm restraints sure are a good idea. 2- the FFR tall rollbars look better and better don't they? 3- Since he was wearing some type of neck collar, I would not have taken his helmet off til he was in the ambulance under a doctor's car.Wow! Sure hope all our track guys watch this and build or modify accordingly please.
