One honest question, as this happened to me years ago on a motorcycle.
Officer pinged my motorcycle as going 44 in a 35. Pulled me over and asked if I knew how fast I was going. I answered 35mph on the nose, as I know the area is patrolled thoroughly. He mentioned I probably had a faulty spedometer and that the "grace" for spedometer error is around 4-5 mph. That being said, he suggested I have the spedo checked out, be wary its reading low and let me go at a warning.
Sure enough, the cable was found to have a kink in it when I had the motorcycle serviced.
Generally, do they really have any sort of grey area for "spedometer error"?
As to the topic at hand...my days of flying along at 10 mph anywhere are over. Its just not worth the fines and punched up inusrance rate risk to me. If you get pulled over and have a dash full of LED lights blinking radar warnings, to me, that just tells the officer you were caught trying. Just me of course.
Edit: The biggest problem I have is that people ahead of my car think its a police undercover vehicle, since from the rear view, my car has that color/profile. So in most of my driving, I'm always driving 24 mph Doh! Dang paranoid bastids!
