OK so why does it matter? I think most people would assume that road rage has two types of negative influences – emotional and physical. For the former, a bad incident would create a chain reaction of ill-will. For the latter, a bad incident would result in a different kind of chain reaction, like a 3-car pile up.
Most Courteous Cities by Safety Rank:
124: St. Louis
Least Courteous Cities by Safety Rank:
139: New York
184: Los Angeles
196: Washington DC
n/a: Boston (I don’t think Allstate insures drivers in Massachusetts)
The numbers appear to be directionally correct: more road rage = more accidents. However, watch out for those drivers in Dallas – they’re nice, but they’ll hit you!
