I went past a speed camera at Pentraeth, Anglesey at about 6pm on the Sunday evening at the end of half-term in October last. This was a particularly sneaky effort from North Wales police, who presumably had some targets to meet and thought that departing tourists were fair game, even on a Sunday evening. The camera was pointing at a steep downhill incline which requires braking to bring speed down towards 30mph so many people must be caught there for 'accidental' speeding.

Road conditions at that time did not justify a speed trap - no parking is allowed and it is a pretty quiet place. Presumably the hardware has been uprated to provide good images under street lighting?
