Merc berk, I hope the police are watching this video and gathering information regarding your behaviour on our roads. You are an idiot who shouldn't be on them.
you cut him up at the roundabout, he got pissed off... I wouldn't be surprised if the dashcam dude flipped him off when he beeped, making him road rage.
Wonder who is browsing this page in so far as I wonder if they're doing it from a car show-room or affiliated interest. See, this is yet another still image with no information regarding the circumstance it was taken or the underlying motivation. In short, I think you are just wasting people's time.
Also... at the traffic lights why was the copper not keeping left, or if turning right indicating - guilty either way?
Its hard to respect those that don't even demonstrate reasonable or even law abiding standards, whould said officer have passed his driving test if driving like that?
This car was filmed on the A41 near Berkhamsted swerving in front of a car carrying a child. Get this person off the road before someone gets killed.
