I dunno, east-coasters seem to have more road rage too. When you get to New York, people are completely and utterly pissed at eachother. Every time I go to Chicago, I notice that drivers all seem to have this underlying urge to kill all pedestrians which we don't get in California.
I spent a weekend in Chicago and saw more pedestrians in near-death situations than in the rest of my life, cumulative. Where on Earth does that come from?
