Can you get pulled for doing that late at night to test your RD? I spotted 2 marked and 1 unmarked Crown Vic's hiding at some dark and empty strip mall parking lots for end of the month I/O ambush. I was in a driving mood and decided to play with them to test my V1. One of the cops probably recognized my car and decided to pull up behind me and hit me with I/O twice. Then he pulled away after seeing my V1 lighted up like a Christmas tree and I was doing 10 under and not going any faster.
Also, can you get into trouble if you flash the oncoming traffic and alert them of the speed trap ahead?
