The speedometers are not very accurate. I noticed this when I first got my car and asked a friend of mine who works at a local BMW dealership, and he told me that the speedometers are deemed "accurate enough" if they are within +/- 10% of your true speed. I know that mine tends to read about 10% higher than I am actually driving.

According to Edmunds, the law allows +/- 2.5% error. Since manufacturers don't want the legal hassle of having a car indicate a slower speed and end up with a ticket, they build the cushion the other way, always indicating a higher speed than the actual speed.

Even if a speedometer was 100% accurate when the car left the assembly line, several thousand miles of wear on your tires will create its own error, since the speedo cannot compensate for the inevitable decrease in tire circumference as your tread wears down.
