How accurate are those speed guns in terms of target at a distance? I rounded a corner about 15 over the speed limit and saw a copper pointing one towards me about 500 meters away. Obviously slammed on the brakes, I was over the limit when I saw him which meant he saw me. Was expecting his pal in the car to pull me. They ignored me, which I thought was lucky and odd. AFAIK they need to be a certain distance in order to be reliable and accepted in court, depending on the model of "gun". Google tells me that a laser-gun has a range of about a mile, whereas a radar version is only effective up to 300yrds. Also - a motorbike at speed is a slightly harder "target" than a car. I am also of the firm (eg. naieve ) belief that many traffic police are "sensible biker friendly", which may have helped your cause
