All of the above and then some. I'm making a left turn. The idiot in the opposing lane is making a right turn and slides all the way into my lane rather than into the proper right hand lane.
Idiots that come into the free way and refuse to speed up past 30 mile an hour for at least a mile after entering the freeway. But the thing that probably takes me closeset to road rage is are the "High Beam Harrys" that refuse to dim their lights, regardless of how many times you blink them to do so. It's even worse now that some cars have to extremely high intensity type headlamps.
