Personaly i think the speeding penalties should be tougher but fairer ie dont put a speed camera on the bottom of a straight 3 in 1 hill on a busy route used by heavy vehicles. Lots of the cameras around are there for cash generating absoloutly nothing to do with safty.
Trouble is people learn where the cameras are and slow down for them to the extreem of doing 30 in a 40 because they dont know the limit even though it is posted by the camera then go speeding off once they are past it.
