The point isn't irrelevant at all Spud, they cost more than a traffic copper, but they can do nothing about drivers who are a danger to other road users and know where the cameras are.
Speed camera - slow down - go past speed camera - speed up again.
I'm not trying to dress anything up here, breaking speed limits in some areas is wrong, particularly in residential areas. You still haven't addressed my point that a lot of speeding is the result of lack of awareness and human error, and committed by EVERY driver at some point in their lives, even with the best of intentions.
They should be punished for this shouldn't they ? The law is the law after all.
I don't disagree with cameras in principle, but I do belive they are being horrendoulsy misused and depended upon.
