Of course, all the more reason to stick to the speed limits and drive sensibly. Anyway, only fitted mine this week and already recorded my first accident (car pulls out in front of boy racer going too fast in 30 limit, Both to blame, no injuries so didn't get involved). I witnessed a really nasty and spectacular accident last summer and as the car directly behind the collision between an HGV and a car was interviewed by the police, would have been great if I'd had it fitted then.
