Shocking moment impatient 'road rage' motorist drives on wrong side of road before swerving into motorcyclist and knocking him off

Dramatic footage - captured on a dashboard camera - shows the moment a rider is catapulted off his bike after the driver of an Audi swerves into him in Southampton. At the start of the one-minute clip, the motorcyclist in dark clothing is seen overtaking a car on the right hand side of a two lane carriageway. The driver of the silver Audi A4 Sport Cabriolet then comes from the wrong side of the road, (top right) parallel to the motorcyclist. The motorcyclist briefly looks towards the Audi, before he is knocked from his bike (top right and bottom left).
