Slightly off topic, imagine you're passing Techniquest on the right, past the car park and zebra crossing, and the round bends round to the right. There's a lay bye on the left - it's actually a bus stop, but last yr. picked up the Mrs late at night from there as it was in a busy area. Got fined £100. Asked for ALL of the camera shots and I was there only 6 seconds ! Appealed and got off, but had a long, personalized letter from Plod telling me off and not to 'park' there again.
Since then [2yrs ago now], must have seen dozens of folk dropping off/picking up there, not knowing there's a camera watching and a £100 fine on it's way..
