How do I make electric car track physics

So I'm making a electric car track game, and need the cars to react to the physics when the car are going to fast in the curves.

I have no idea how I'm going to do this. I've made a dummy object that follows the rails and attached the car to the dummy (with a distance joint), but the car only follows. Its not spinning out of control when it runs to fast.

Any ideas?

is that not a flexible joint on a moving pin point?

Yes, but Cant get that to work.

This should use a limited revolute joint rather than a distance joint. You might want to share the .capx if you want further assistance.
