So how many of you would have the brass ones to install this:
Here's the thought. You have a lidar detector. You know with great certainty where officer friendly is going to be aiming his lidar gun (i.e. your license plate) and that in order to target the gun he has to aim it using its sight, so he's also looking there.
Why not rig up some LEDs or something to flash a little message to him every time your car gets hit by lidar. Could be just a "Hi There!" could be something ummm more inflammatory. It would probably be a good idea to switch it so you would only let it trigger when you know you're well under the limit.
I just got done driving through horrible slow traffic and got pegged by lidar at like 15 under and crawling and automatically said "Hello Officer" to myself under my breath and had this idea. I should get out more.
