That explains all the safety cameras outside schools.don't get why so many people are bothered about stopping people who are breaking the law get caught. Speed limits are set at a limit for a reason and that's safety.
Oh wait, there isn't a single one in existence in front of a school, what could they all be for?
When mobile cameras start parking next to well known blackspots instead of the 40 to 50 transitions, then you have a valid argument. Until then they are purely a cash generating mechanism.
FWIW I no longer deliberately speed, but the existence of speed cameras has no bearing on that and never did.
