I recall that people took the car more, and the plane less, in the aftermath of 9/11. At least partly due to the inconvenience caused by the new security measures at the airports. 5 years later, this increase in road traffic was estimated to kill as many people as were originally dead in the twin towers. Just because people chose the car a bit more, and the plane a bit less.
