Many years ago, one of the car magazines did a test of radar absorbing panels. The attached flat radar absorbing panels* onto the front of a 911 and tested how various radars locked on to the car. Completely impractical, but a fun test. There approached the radar at a set speed of around 35 MPH and measured where they got the lock. During one of the tests, the radar suddenly locked on at 65 MPH. Then they realized that an 18 wheeler had just crested the hill, and the radar had locked on it even though it was very, very far away.
The point that they made was that if you could make your car "invisible" to radar, you could end up getting someone else's ticket since the cop would think they were clocking you. Then they commented on the fact that if you were going to go to the trouble and expense to make you car "invisible", you would probably be better off with someone else's ticket anyway...
*The test used flat panels of radar absorbing foam of some kind. Not water proof, ugly as all get out, and very expensive.
