I'd jump on that 2mph claim. Someone on my local forum, responding to a similar thread, suggested the suspect ask the office for calibration records for the radar gun, since they usually don't keep them calibrated and even if the guy clocked you the numbers could be thrown out.

If he says he knew by "visual estimation" you might think about asking how far away you were when this happened. I don't know if this would work; it's just a thought.

X2 on being honest about hypermiling and bringing in fuel logs.

Good luck with this. Many people driving modified cars will treat over-tinted window tickets and the like as a "pay to play" kind of thing and not worry about it. Hopefully this doesn't become the case with hypermiling.
