What does the speedometer of a car read?

The speedometer of a car shows its instantaneous speed (as we understand it) and not the average speed.

Technically, instantaneous speed is also average speed, but calculated over a very, very small time period.

Speed is nothing but a ratio of distance traveled and time taken.
