The opposite effect happens as well: https://www.schneier.com/blog/archives/2013/09/excess_automobi.html https://www.schneier.com/blog/archives/2013/09/excess_automo... > The inconvenience of extra passenger screening and added costs at airports after 9/11 cause many short-haul passengers to drive to their destination instead, and, since airline travel is far safer than car travel, this has led to an increase of 500 U.S. traffic fatalities per year. Using DHS-mandated value of statistical life at $6.5 million, this equates to a loss of $3.2 billion per year, or $32 billion over the period 2002 to 2011 (Blalock et al. 2007).
