Eeeelllo elllo what do we have here then? I see the down-voters have descended upon us again. Unfortunately for you (and whichever "force" you may or may not represent[!]), society will decide for itself - not you. Nice try, but poor show..better luck next time.

Van driver clearly in the wrong but it did seem like the car driver was putting himself, his girlfriend and other road users in danger by chasing after the van. I understand the need to get his registration number but there was every chance that it could have made things so much worse with some of the risks taken to keep after him. Shock, anger, red mist, we've all been there and I probably would have had the same reaction, but still.
