Speedometers were first used in every motor vehicle in 1910 to determine the speed of which the vehicle is traveling. This little piece of device is very helpful for drivers up until now.

However, do you know that most speedometers have a 10 percent margin of error? Yes, the speedometer you are using today might not be accurate because of tires wear and tear and tire sizes that are not standard. So if you happen to have an old speedometer it is high time that you get it calibrated or better yet get a new one to have a more accurate reading.
