Now that I stopped laughing, I conclude that this is a fake. The car that the kid hit vanishes just after the camera turns to where he would've laid. Also, the neighborhood seems to change from some brick houses to houses with white-ish siding as well as the grass becomes greener.
EDIT: The door closes when the kid falls out because it hits the parked car, but at the end of the footage, we see that the door dosent have a scratch on it. Stop me if I seem repeatitive.
