It seems to me that many drivers have a "bubble of unawareness" surrounding them, as they blithly drive along at 10 or 15 miles above the speed limit, changing lanes without signalling and talk on their cell phones or to their driving companions (or both at the same time). For me, driving in the West, where traffic rules are basically unenforced, has required a refresher in defensive driving.

On the other hand, road rage is pretty uncommon since this kind of driving is the norm here in Albuquerque. We did have an odd case about two weeks ago...a pedestrian apparently took issue at the behavior of a driver, followed him into a copy shop near the University, and shot him. No permanent damage done.
