Dramatic dashcam footage captures the moment an angry car passenger attacks a motorist by pelting his car with a plastic bottle. The pair were involved in a bust-up as they approached a junction close. A bearded man travelling as a passenger in a white BMW, leans out of the window and hurls a two-litre bottle of water at the windscreen of the other driver. The victim's dashcam camera captured the whole incident - with the bottle cracking the bottom of the windscreen. The BMW shot off afterwards but the badly-shaken victim has made the footage available to police to deter other road rage thugs by showing how their behaviour can be caught on camera.
