I had this happen to me once in Oakland a couple years ago. Guy drivign a pickup way under the posted speed limit for no reason (like backing up traffic 6 cars behind me), get to a stop light. When it goes green, he sits there (he was going straight through intersection, no traffic), so I give literally a quick honk of my horn to get his attention. He moves like 5 feet, stops, gets out of his truck then punches my driver's side window, exactly like this crazy woman in the video. I didn't have time to get my phone out to record the event. Wish I had. These people have issues.
