How to reduce speed on a speeding ticket?

Question Details: My son got a speeding ticket on I-84 from a CT State trooper. The trooper came up from behind and pulled him over. He got a ticket for doing 85 in a 65 mph zone. No radar was used, the trooper based the speed by following him. My son pleaded not guilty hoping to reduce the speed down. What is the best way to do that? Note - his car was hit a few weeks prior to getting the ticket. Front passenger quarter panel is pretty dented but OK to drive, however something that would prevent him from doing excessive speeds. Is this a valid argument or should I argue that judging speed by following a car is inaccurate?
