That is my understanding as well. You leave the vehicle in a hurry in a motorcycle crash. The fire resistive rating is in the event of a fire in the car.
Quote:My understanding about helmets is that the SA units are made with Nomex for fire resistance while the motorcycle ones are not, thus is why the SA ones are more expensive. All helmets are made to take impact, ONCE, so it is best to replace after a crash since it may have an invisible crack that may compromise its function for the NEXT time. Usually a lighter (carbon kevlar) are considered the best for strength / weight. The lighter weight has less SNAP momentum in a crash, and the Hans and R3 head restraint systems help the neck muscles to maintain your head over the shoulders.
