Sure he can and very easily. He is driving 40 mph. His radar show you moving away from him at 15 mph. You are driving 55 mph. Also, many new radar units are tied into the vehicles computer and can show the actual speed of the vehicle in front of the officer, even while he is accelerating or slowing down. Please don't use this as an excuse in court, it will aggravate the judge and make the attorneys present start laughing.
Anyways the point is he CANNOT radar me from behind and chasing me.
If you feel my answer is rude, mean, snarky or in anyway not to your liking, I did my job. You don't need to tell me.
