If you're on your way to vote, be careful. According to a report in the Journal of the American Medical Association, you are about 18% more likely to die in a traffic accident on presidential election days than on any other Tuesday. Why?
One explanation is increased traffic, but other factors might contribute. A 4% increase in average speed, for example, could yield an 18% increase in deaths even with no increase in average travel distance. Additional factors might include distraction (driver inattention), rerouting (unfamiliar pathways) enforcement (decreased police presence), and demographics (mobilizing unfit drivers).
Man, I love scientific research.
