Be honest - are you a good driver? Do you get road rage? Do you hate driving, or avoid it altogether?
Arizona's drivers are pretty oblivious. No one users their signals, they speed 20 miles over the limit. On top of that, we get the snow birds who migrate here for six months of the year who drive 45 miles an hour on the freeway and 30 miles an hour on the city roads. Awful.
That being said, I'm a pretty vocal driver. I don't necessarily yell at other people, I just kindof yell in my car and use hand motions. It makes me feel better.
