I know what you mean. Cops are an annoyance. I was driving the other day coming off a roundabout and a cop car was about to enter the roundabout from exit I was taking. As I came off I looked at the cop car (Maybe a stupid thing to do) after that it took off and went around the roundabout and followed me for a few minutes then they finally stopped me. They treated me like crap cause I was a young looking driver. They held me up for about 5 minutes checking my drivers details and got me to do a breathaliser and all this other stuff.
