Torque3D game with soft body physics and vehicles. It is supposed to be a "Soft-body physics vehicle simulator capable of doing just about anything." but most people just crash their cars in funny ways, which made this game so popular.
I played an early demo and though crashing the car was fun, I was not able to survive very long, like driving one round without completely wrecking my car, which is probably either not very realistic, or I'm just a very bad driver.
In the meantime the game has come a very long way and has lots of new content and they even have missions now and you probably survive driving one round with our car without wrecking it, as I have seen other people doing it. So you can do other things now than just crashing your car, though most people still only care to crash their car.
