I have a 3 week old TCH, about 1200 miles on the odo...I THINK! (maybe it realy only 1100) LOL Anyway, our town recently put one of those raodside radar machines that says you are going "XX"...

Well, when I go by the radar at an indicatded 35, the radar says 32-33, also about 3 miles per hour. I am a little concered by this inaccuracy also, as the reported MPG will be higher than real as well. I always wonder if I am driving too slow now that I have fuel economy at the top of my mind,even when i am driving at what I THINK is the speed limit, and am being tailgated constantly. Perhaps If I increase my speeed by the apparent 10% inaccuracy than I won't get tail-gated as much?

I wonder if it is just off by 3mph at all speeds (or is it 10%) as the above poster indicated his was off by 3 at 60mph?
