It's interesting how speeders are sneaky breaking the speed, only to hit the brakes if they see a police car and or camera.. If they stuck to the speed limit such sudden braking and potential bad practices could be avoided. I laugh at the twits who race by, then all of a sudden hit the brakes when they see a camera, then after a 1/2mile race of. But then it's their licence, penalty points and higher insurance premiums at stake.. People bleating on, cameras make money have themselves to blame. Stick to the limits and camera will take in no money. So it's the motorist who feed these machines..
