There's nothing like getting mad at someone else over your own bad driving.
The finest example of road rage/douchebaggery is when the person who is at fault is the first to lose their temper. This is how the video here starts, with the guy who has been driving like a dick losing his mind and Bruce Lee-ing a car which he had very nearly hit. The owner of the now damaged car decided to retaliate, and although the original perpetrator of the road rage punched the car one more time, this is weirdly where he seems to give up.
The decision to give up might have come from the fact that he was now feeling those other punches in his hand, or perhaps it’s just as seemingly illogical as his initial decision to freak out. We just don’t know.
