People don't use cars to travel thousands of miles - especially as this topic was about speed of travel. So this per-mile statistic doesn't make flying any better as a form of travel. It's like comparing safety of moon rockets vs bicycling per mile of traveled. Secondly, the co2 injected directly into the upper atmosphere has ~3x the warming effect as co2 emissions released by cars. If we look at an hour of flying vs an hour of driving, the air traveler contributes 20-30x as much to global warming. Of course 1-2 passanger car travel is horrendously bad as well, especially if you do it daily...
