It's not well known, but having retired from Ford, I can tell you the margin of error on your speedometer specification is quite wide...the industry standard is +/- 5 mph...which is very generous. I was refused warranty work on my speedo because it was only 3 mph off..... On a 3 year lease car with 12k miles/year that can add up to hundreds of miles!
I received a ticket in Illinois when I was a teenager for spinning my wheels as I was leaving the local high school hangout. The cop couldn't ticket me for speeding so he gave me a ticket for "exhibition of speed". Who ever heard of such a thing?
Laws written versus laws enforced is a huge deal as well.
In Michigan, typically you can go 5 mph over on surface streets and 10 over on freeway (freeways that are 55 can be treated like they are 70 sometimes as well).
But obviously at any point you CAN get a ticket. Will you, probably not, and if you do something like go 15 over, will you get a 15 over ticket, again probably not.
Stop signs are the same way, sometimes you need to stop. Other times a California Roll, as they call it, gets you by.
But it is always up to the discretion of the officer.
