Does police radar/lidar show simply the closing speed to the cruiser or does it correct for the angle of approach?
We have a stretch of highway in Cleveland (I-480 from Hopkins to the Turnpike) that is notorious for having speed traps. I have noticed that when the officer(s) is/are on the left berm/median, they usually set up where the road turns gently to the right. If they set up on the right berm, they are usually either hidden by a bridge support or where the road turns left. In other words, they seem to set up to get a more head-on shot. It could also just be that those locations have the highest yields and the selection is not intentionally based on that hypothesis.
