The definition of acceleration is: Any change of velocity, that is, speed
or direction of motion.
If an object is undergoing constant acceleration, then the definition says
that its velocity must be changing.

No, when a body is moving with constant velocity then neither the magnitude nor the direction changes, and that's exactly the definition of zero acceleration.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
If there is acceleration (uniform or otherwise, but non-zero acceleration), the velocity changes. Constant velocity means that the velocity does not change.
It's not. If you speed is constant (but not zero), then your velocity won't be zero, either.You may be confusing this with the following: If your VELOCITY (not your speed) is constant, then your ACCELERATION is zero. Acceleration refers to how quickly velocity changes, so if velocity doesn't change at all, acceleration is zero.
Acceleration is constant.
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.

Constant acceleration
if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.
No. Since the direction changes, so will the velocity.
