I adjusted the camera so its farther away from the car and this seemed to have helped quite a bit but it still gets stuck a lot, even on perfectly flat terrain.

Im going to get gamebuilder and use the terrain tool they have to convert my terrain into blocks. I think this may solve the problem. I won't be able to work on it for the rest of the week but I'll come back next week and let you all know if a terain made of blocks is what you need to get the car project running.
