BTW...every speedometer will have a certain amount of error, and typically GPS is not the best indicator of true speed because there's a couple second delay time, sometimes they only update every 30 - 45 seconds.
yeah, this guy isn't winning any genius grants any time soon. I have never heard of a speedo reading that much LOWER than actually speed, I would ask for calibration records of that radar gun.
