WOW, deja vu. I had similar thing happen at 17 as well (I'm 33 now). I had an old chevy musclecar. It was december, and cold. Anyone who's owned a 60's vintage chevy, knows they are the cold bloodest cars in the world. Well, my car was fast. VERY fast. But I always kept her within the speed limits. I had just left the school (mind you my car was still cold, no heat yet, and barely going). I turned from overpass (sitting at a red light mind you and having to put foot on gas to keep her running) I had a police offer behind me at light, and no I wasn't revving engine, just stepping on gas a bit (Won't disclose city name, but they were notorious for writing tickets in the 70's and 80's). Well, I had barely turned, and was about a block from the corner and he turned on his lights. He said he had PACED me going 65 mph in a then 40 zone. I laughed (since my car died when I pulled over, it was still cold). My car would not run fast until thoroughly warm. Had no umph at all cold. He didn't tell me that he paced me until I asked him to show me radar (my basketball coach was a lawyer thank god, in fact he's now the judge of SAME town lol). He represented me in court. Put officer on stand (which, he was one of the bad ones, this city actually had a lot of them) and ripped him apart. Back then, legal pacing had to be 2 city blocks worth. This was barely even one, I had stopped within the end of 2 blocks. The fact my car was cold and I had turned a corner to start my pacing was another factor. It was actually thrown out of court by the judge. But, I had to deal with the terror of my parents up until court date. But in end, the judge even chastised the officer (which I had heard was rare). My lawyer even said that, and figured it may have been a ploy since there wasn't any other cases that day, I was the last.

So, go and fight it. It saved my insurance, which a male under 25 needs every break they can get. I agree, get a lawyer. What's the saying "A man who represents himself has a fool for a client"?
