Death by airplane is "someone else's" fault. Death in a car is my fault. Even if someone else was negligent, it's still my responsibility to compensate for their idiocy. This is the Merican way. Personal freedom, choice, control, and consequences. I deal with this every day as a motorcycle rider (the ultimate in personal control and consequences).
The simple fact is, on a commercial air-flight you have absolutely no control whatsoever over your death. As a driver of a car, you do, even if it's someone else's fault. In other words, flying on a commercial airplane requires no skill, driving a vehicle does.
