Wow, that sounds like some serious road rage, cut the wheel all the way to the right and throw it in reverse. I was riding with a friend when I was in high school one time and a random pedestrian flagged him down and then punched him square in the face through the window, for some reason strangers were always punching that kid in the face.
I've never had anyone get out of the car like that thank God, I wouldn't want to harm anyone.
