joe-90 - i think you're missing the point. No-one is saying that driving slowly doesn't save lives - what they are saying is that speed cameras don't make people slow down and therefore don't save lives. 1000s of people get 'done' by speed cameras so they obviously don't make people slow down. Personally i stick to speed limits because i know that i'm so unlucky the one time i do 3mph over the limit i'll get caught so i do 30 in a 30, 40 in a 40, etc, etc
I came up with a brand new idea the other day, why not link speed cameras to traffic lights 200 yards down the road, if you're speeding past the camera, the lights go red and you have to stop. Therefore it'd actually take you longer to get where you're going than it would if you'd have stuck to the limit!?!
