I answered that it measures a vector quantity my rational being that it is the instantaneous speed in a forward direction, always. It doesn't matter if the car is turning the measurement on the speedometer is always going to be instantaneous speed in the tangental direction right? It's not like it's a measurement over a given amount of time because instantaneous is taken with the limit of t approaching 0 right? I'm not entirely sure if I answered correctly though but I still stand by my answer, it makes sense to me atleast.
