When you drive a car in a circle at a constant speed you are accelerating towards the center of your circular motion.

True

Explanation:

The given statement is true because when we drive a car in a circle with constant speed , the car experiences the centripetal acceleration towards the center.

But acceleration is change in velocity of object in a given time, here direction of velocity is constantly changing to give rise to acceleration.

If the magnitude of velocity is changing with time then the car would have experiences the tangential acceleration .
