A study analyzing the driving behaviors and habits of severalmajor metropolitan areas concluded that Miami, Fla., has the rudestdrivers in the country, while Portland, Ore., has the nicest.

The list of cities with the least amount of road-rage issues sawmuch more movement, however. Following Portland in drivingpoliteness was Pittsburgh, Seattle/Tacoma, St. Louis, andDallas/Ft. Worth, respectively. Only St. Louis and Seattle/Tacomaappeared on 2006's list, too.
