Why are speedometers inaccurate?
I've noticed that my car's speedometer isn't always accurate. Do you know why that happens?
Yes, speedometers can be inaccurate due to several reasons. One reason is that they are designed to display a higher speed than the actual speed to ensure that drivers don't exceed the speed limit. Additionally, changes in tire size and air pressure can also affect the accuracy of speedometers.
