You seem to be missing a reference to both VehicleController and VehiclePhysics, if you’re using visual studio you can simply tap alt+enter while highlighting the class name and it will pop up with the path.
As to why each one doesn’t work:

TheCar.GetComponent<VehicleController>().enabled = true; //not work

The reason you can’t access ‘enabled’ is because of the missing references, as the script can’t see if the component you’re trying to access ‘enabled’ on derives from MonoBehaviour, add a reference to VehicleController and you should be good.

TheCar.GetComponent(VehiclePhysics).enabled = true;

this will not work since you’re trying to use the typename as the actual type try to use TheCar.GetComponent(typeof(VehiclePhysics)).enabled = true;
instead.

TheCar.GetComponent("VehiclePhysics").enabled = true; //not work

You should never do this unless forced to, as the syntax using the type is preferred, but if you are forced to do this, try casting it to the type you want (TheCar.GetComponent("VehiclePhysics") as VehiclePhysics).enabled = true; or ((VehiclePhysics)TheCar.GetComponent("VehiclePhysics")).enabled = true;
Hope that helps a bit.
