A girlfriend of mine lost her 16 yr. old son in such an accident. He ran a stop sign and his body went through the back seat, but his head went over the top of the car. About 6mos later she visited me and I took her to a resort town to relax (yeah I know, don't say it, I was a gentleman). As the wine began to hit her, her eyes began the 1000yd stare, with tears.
Motorcycles are in the same risk class as guns. Going fast or bending roads won't kill you, it's carelessness and craziness that will. Like guns, one really needs to be taught to ride, even if one can "drive" a bike.
