Same thing happened to me last week.. My first day out for 2010 and I got stopped by a State Policeman. The ticket says he 'paced' me. He said it took him 10 miles to catch me and I had to have been doing at least 110MPH..
The only thing I know is he pulled me over.. I got 80 in a 55, and illegal lane change. Traffic court on 4/21 for me. I felt the same way what a start off to the season. Good luck fighting it...
