    Speedometer of car read instantaneous speed of course. Its because when you stop it instantaneous show 0. If speedometer show average speed there should be different value than 0 (much greater) just when you stop.

    Maybe there are car with speedometer with average speed but the time from which the average is taken is extremely small. Its simply instantaneous speed.
