Same thing happened to me this past Friday in NY. Cop had been following me for a bit, so he racked up five things that he could bust me with: 64 in a 45, lane changes without signaling (2x I think), no signal with lots of traffic is endangerment I think and tailgating on a couple occasions. He said the five tickets would have run me 14 points and lost my license. I talked to him and was really polite with him, which is what you need to do, and he ended up giving me two tickets: 64 in a 45, and one signal change for a total of 7 points. Guy was nice, there's no doubt about that, I just fucked up.
I voted "This topic is stupid" because I was going to do the same thing when it happened, but I realized that it would be pointless and you just have to live with these kinds of mistakes. The 200 bucks spent on tickets will be a nice addition to my Banshee.
