Footage of the moment a car was sent flying at 160km/h on a busy motorway has emerged.
The crash happened during a road rage incident that saw two cars repeatedly undertake and tailgate each other on the M4 in Wales.
The footage of the incident was captured by police dashcam and shows a blue Mini and a Ford Mondeo going head-to-head.
The Mini then speeds off to the left of the motorway, hits the barrier and flips on to its front.
The vehicle then overturns and spins across the motorway.
