unity3d model rises on play

Unity3d problem:

My terrain and car both have rigid bodies that use gravity.

When I push play it looks like the scenery/island falls away or either the car rises. Since the transform y-coordinate changes when the car rises, I’m assuming it’s the car that is flying away. It is supposed to stay on the cement ground.

Any ideas? Thanks.

Why do you have a rigidbody with gravity on your terrain ? Sure the earth is attracted by the sun, but that’s pushing realism a bit far. Remove it.
