Diazepam, I suppose statistics about death don't really matter, it's the fact that a plane crash is the worst way to die. So many incidents where the plane stalls and falls out of the sky or sets on fire turning into a giant crematorium where people know of their impending doom and linger for many minutes. A car or train crash on the other hand is something that happens in an instant, no where near as bad. That's what creates the fear I think. Between a higher chance of instant death, and a lower chance of an horrific nightmare experience I know which I'd choose any day.
What about if you were in a car crash and the car flipped over and you were stuck there upside down with fuel leaking out and you are like that for ages hoping it doesn't catch fire? Then it catches fire and you slowly burn to death.
Dying in a car is no picnic either.
