The only issue I have with your post (because I am 100% with you otherwise) is that traffic Radar IS accurate to within 1 mph. While it IS true that it can return a reading of less than your actual speed, it will not return a reading of more than your speed.

I certify traffic radar as part of my job. Every Kustom and Decatur radar out there rounds down to the nearest 1 mph. The circuit measuring the doppler effect is VERY accurate. And in Georgia, the unit itself has to be certified as accurate once a year. In nine years of certifying radars, I have never seen ONE of them inaccurate. I HAVE seen them come in with defects that cause them to have poor range, but have not seen one that is inaccurate.

Even so, a 1 mph ticket? Total bull ****.
