This is why some people shouldn't be allowed play video games. Because they take the inconsequential dickhead behaviour into the real world and expect there not to be any trouble. But how wrong they are.
The driver in the black SUV hit the white taxi before the video starts, and tries to do a runner when the taxi driver demands insurance info. Mr. taxi driver however is having none of it and tries to get the driver out of the SUV, which results in vehicular carnage of epic proportions.
How sorry do you feel for the four other people that suffered thanks to this gobshite? (According to local blog Chicagoist, Turns out the SUV was actually stolen, hence the aggressive and careless behaviour, and the driver was later arrested by police for the offence. And he did over $3,000 of damage to the taxi alone.)
