Why when there is a 20mph speed limit do some people think it doesn't apply to them. I was overtaken today in the 20 zone by a white crew minibus with a local builders firm who has their name on the side who went so fast it sprayed my car in stones. I hope the driver is proud of himself didn't get his regisration number as he was going too fast. I hope his boss is reading this and tells him to obey the rules of the road.
