Don't listen to Chav, no one else does. Traffic lights are the automated authority to progressing at junctions and jumping a red light can cost much more than time. I have heard of many incidents like this lately and it is not going to be long before someone gets killed and it could well be any of us.
I've got a dash cam with lots of incidents of people going through red lights and may prove useful when one day I may need it for evidence. It's a small investment as insurance companies like to go for 50/50 responsibility in alot of claims which makes both parties responsible and so you have to pay up the voluntary excess and not get it back. As my excess is £300 it is well worth getting a decent dash cam like the Roadhawk.
