If a car travels around a corner at a constant speed reading on the speedometer, what must be true about its velocity?

Answer

Its velocity is non-zero but changing due to a change in direction

Because velocity includes direction, a change in direction inherently means there is a non-zero acceleration, even if the magnitude (speed) is constant, as seen in uniform circular motion.
