    The car I use is from unity standard asset. It can move normally. However, after i added a trailer for it and hinge joint/character joint, the wheels are spining but the car cannot move.

    Both of the car and the trailer have 4 wheels collider and box collider.

    If I set a very small mass of the trailer (not a good solution), the car moves. It seems too heavy for the car.

    I have seen some one have the same problem. He use a script to solve, but I dont know the language and the script content.
