Federal standards for car spedometers allow 10% error. Because of liability, cars are not sold with spedometers that read low.
If you are less than 10% over, the cops would need to prove that you knew it. This would involve testing your car. Nobody wants to bother with that, so you normally get an extra 10%.

There is no such need for cop to "prove" you "knew" you were speeding. Ignorance of the law (or the condition of your vehicle, or whatever) is no excuse, as the saying goes. When you sign up for a driver's license (in the US) you agree that you will abide by all traffic laws.
