A car windscreen was smashed with a wooden batten in an explosion of road rage in Tauranga yesterday .
The mid-afternoon incident reached boiling point when the leading car stopped on Cameron Rd's outside south-bound lane, opposite McDonald's playground near the 11th Ave intersection.
A witness who spoke on condition he was not named said that when the car stopped, the car coming up behind had to stop as well.
He then saw a person in the front car get out, walk up to a man in the passenger seat of the other car and "start swinging".
The driver sitting next to the passenger then got out and joined in a melee which ended up with the passenger and driver fighting the person from the front car.
