I don't care what you think. I'm not a racer and I don't normally speed. When I do go over the limit it is because I'm not thinking about it. If I wanted to get away with going fast I would employ other means.
You can get an Eroad unit which has posted speed and on screen speed so you can maintain your speed a lot better and have an audible warning when you go over the areas speed limit. Then you are not in the wrong.
I'm not bothered if people think I use a radar detector to break the law, but another reason I like it is because it gives me a (very) slight sense of power. Knowing where the police radar cars are even if I can't see them is a kick, albeit a very tiny one. It is like going nyah nyah I know something you don't. It appeals to the child in me.
People have police scanners for the same reason. Not because they intend to rob a bank, but because being able to listen in on the police makes them feel like part of a secret club. It is relatively harmless.
