*Some* Rigidbodies Fall Through Terrain

Hello!

I'm having some problems...

I have a car with the scripts etc. attached. If I create a cube, it falls and hits the terrain just fine. However the car simply falls through the terrain. I have a collider attached. See the screenies.

Anyway this also happened with some other rigidbodies I was using. These were switched from isKinematic = true to isKinematic = false. None of this is happening with this car.

Here's the pics.

Hard to tell from the pics (too small), but if the car is using a mesh collider, that won't work. Use a primitive collider (or compound primitive collider) for the car instead.
