Since I got my license back around 99/2000 time it took me up until a few years after leaving the UK to get my license clean, got caught quite a few times and since its been a while since I went back to the UK I've heard its really bad with undercover cops/cameras on m25 etc. I'll find out later this year.
I was driving in upstate NY a while ago following a bird in a civic when she moved over from the fast lane and the cop got me, let her go even though she was going faster than me. Had to send letters and have a court appearance and in the end got fined $105 with $95 in court fees, it had got busted down to littering so they was able to keep the fine amount rather than have to send it to NYC. Its just all one big cash cow here, everything costs a fortune where a car is concerned.
