Went for a drive on a dual carriageway - there was a police 4*4 with big flashy sign (think it said police or something) and looked like it had some sort of camera sticking out of the window (not sure)... was in slow lane and was doing around 76 - 78mph.. (looked like loads of other cars were going faster and overtaking me etc)
Do these stop people?
Do these take photos?
Am I likely to have have anything to worry about?
God I really am getting super paranoid........
