While I'm at it, I will add something funny.

The cop clocked me at 52 in a 40. I had my belt on and all my paper ducks in a row. I was polite and calm. I said 'sir'.

He said, "you know, over 10mph is 2 points on your license and about a $295 ticket, but have you had your speedometer calibrated lately?" Me, playing dumb, "calibrated? Huh?" Cop, "yeah, you look to have larger than stock tires on this thing and that can make your speedometer off by a few miles" Me, "oh really? (laughing inside as I hope he doesn't see my ScanGuage with MPH clearly visible )". Cop, "yeah, so, why don't you take this thing into the dealer and see if they can calibrate your speedometer, might make a big difference. Then you can bring your receipts into the courthouse and present them to the judge and maybe they will drop the point and reduce your fine". Me, "Oh ok, maybe I'll do that, thank you, officer". Cop, "so, in light of that I am only going to cite you for 45mph which is only 1 point, so it won't get reported to your insurance." Me, "ok, thanks". (like he is doing me some big favor, which I suppose he was, by cutting me some slack, but I would say he is actually doing his conscience a favor).
