I certainly don't have much to add to this thread.....but I'll answer the OP's question.
No, at present I do not use any sort of radar detection device. Why? Because I have a negative feeling toads them. For me they are a tool to assist in the violation of the law. I'm not comfortable with that and I would not think it ethical. But do I speed? In general terms not intentionally, no. I have gone over the limit for safety reasons (the avoidance of others driving erratically or some other rare instance). I think that if I was to have a detector in my vehicle (besides feeling unethical), I would have a temptation to break the law. So no, I don't want one nor do I have a need for one. The few individuals that I've known in my life that used them have the sole intention of speeding without suffering any legal consequences. As a matter of memory, every one of them had great difficulty in driving the legal speed limit for some reason. I have no such issue.
