Even after adjusting for miles (or hours) traveled?

I don't think comparisons can be drawn there. It's impossible to do a 2000 mile drive in a day. I regular do two of those flights. Likewise, there are not many 20-minute flights.

It seems to me that the only relevant statistic is likelihood of death per embarkation.
