>San Antonio, Texas without a doubt. Nine out of ten drivers have a cellular phone glued to their ear while driving below the speed limit in the left lane. I have no doubts about the origin of road rage.

Unless laws have changed, the legal availability of loaded weapons and open alcoholic beverage containers in motor vehicles should've reduced the population of rude drunks on the road in TX by now, but then the last time I was in San Antonio was when I lived there 19 years ago...
