lol. agree with all.
My guess as to why the rider did it... he was following for a while waiting on this driver to MOVE OVER. For the biker to be that aggressive, he was probably the one initially tailgating and/or flashing lights trying to get the car to move over. When the car didnt, thats when he came around and messed with the car.
SMH. yeahhhh.. cant win against a cager
