he wont send you a fine, they just say that t get you scared so you dont do it again, undercover cops cant really do anything but pull you up for rbt, or pull you over to check out your car. I get harrased every day i go out, but a few nice words, a few "YES SIR's" never goes astray. remember that for nevet time, and next time he asks you why you were speeding always make sure you say," im sorry officer my eyes were on the speedo and i never went over 50" that way if he recording your conversation he cant fark you later on.
