BMW passenger jumps out of car and PUNCHES another vehicle on dual carriageway in bizarre 'road rage attack'

This is the bizarre moment a BMW passenger jumped out of a car and started punching another vehicle in an apparent road rage 'attack'.



The incident was all captured on a motorist's dash cam as he followed the two cars around a busy roundabout in Northolt, west London.



Appearing to be in the incorrect lane, a driver in a white VW Tiguan apparently began to indicate and changed lanes on the roundabout.



The white BMW was then captured braking and swerving out of its path. It is unclear if the white 4x4 had seen the motorist before changing lanes.



The two cars continued until they were stopped at red lights.
