That guy deserves an award. No way I could just sat there and put up with that shit. Don't get me wrong, I've been that angry recently after a traffic accident, but it wasn't a fender bender.
This would have been a great opportunity to reach into the console and brandish the biggest pistol that guy could afford. Not point it at him, just show it once or twice until the authorities arrived. Especially if it was being recorded. I'd love to see the look on that guy's face after he observed the business end of a firearm. Also, it should be noted that said pussy didnt start going psycho or make a real attempt to get into the car until people showed up to "restrain him".
