See, take it from an actual officer ^. Cops are not dumb they will keep changing places just for those idiots out there who are like "hey, cops usually tag people here so i'll slow down" then you speed in another area and get your ass tagged and are shocked saying "what! how did you, how could you, but you always tag people over there". Your best bet is to A) Not speed B) Be very aware of your surroundings C) Invest in a very very good radar.
