It's actually worse than that. Since 9/11 and the birth of the TSA, a number of people who need to travel a moderate distance (say, a drive of a few hours) have chosen to drive when they might have chosen to fly before. Air travel is statistically safer per mile travelled than driving. I don't have the link handy, but it has been calculated that this change in travel habits has resulted in an increase of driving fatalities of over a thousand a year. More people have actually died in traffic fatalities due to the TSA than died on 9/11.
