Vehicle on turntable not turning.

Simple problem. I have a turntable that I rotate in code with:

Turntable.transform.Rotate(Vector3.up*(Time.deltaTime*30));

And I drop a car onto that from about 2’ up. Car lands on the turntable, but doesn’t spin with the turntable. It just maintains it’s orientation.

On a side note, if I rotate in other directions, the car does rotate with the platform until the turntable is sideways, and then falls off.

add a rigidbody to turntable and checkbox kinematic or add little bumps to teh turntable
