If I was a betting sort, I'd say Berkeley, CA or Atlanta, GA, those are the only two places where they are more incompetent (Berkeley) or rude/aggressive (Atlanta), than they are in CO. Granted, not all of CO is equal: Boulder has a monopoly on the worst drivers in the state, bar none. Soccer-moms in their Range Rover, texting, while ignoring the fact that 4-way stops apply to everyone, including them, is rather sporting....it takes defensive driving to all new levels![]()
