Slippery probability

[briarwood]

I keep reading that you are statistically far more likely to die in a car accident than in a plane crash. But does this oft-quoted statistic take into account how often we do these things? Most people drive every day...I don't know anyone who flies that often. (Superman does not count.)

If we calculate those odds based on each journey instead of a lifetime what would happen? I suspect planes would still win on safety but not by much.
