Between pepper spraying passing motorcyclists and loitering on our favourite roads with speed guns, the police get a bit of stick, but the officer in this video is one of the good guys.
Filmed in South Windsor, Connecticut, the driver in question tries to merge with the traffic and bully the rider out of the way – all the while completely ignoring his hand gestures and frantic beeping.
Shortly after the driver has merged behind the rider, he spots a policeman in a car park and describes what just happened. Without hesitation the officer engages his blues and twos and drives after the driver, telling the rider to follow him.
Of course the whole thing could have been avoided if the rider filming just took a deep breath and let the car in, but it's also another exaple of onboard cameras catching bad drivers in the act.
