Version 1.13 made cars more unstable than before. At 1.12 they were better. Strange errors have happened. I played a FarmingHoe in a garage where there was a car, and the car was completely destroyed. On another occasion, I used my car to unlock another car that was locked in a fallen tree, I tilted my car against the other, slightly, and started pushing, and this other car at one point made a destruction sound and was totally destroyed, furthermore your driver died. You can even include a feature so that one car can tow another car, with a rope, to help remove cars stuck in obstacles, ditches, rivers, etc.
