Unity Multiplayer with mirror and car collision physics issue

Hi guys, i'm trying to make an online racing game with Mirror but I'm new to unity and t$$anonymous$$s Framework..so i've some difficulties.

The problem is that whenever one player $$anonymous$$t the other one, the player that was $$anonymous$$t is like a wall..in single player mode, with the same prefabs, the other car moves on collision and eventually flip over, but in multiplayer no.

I add a network transform to the car prefabs. The car has a rigid body and 4 wheel collider. I apply torque to them to move the car. I don't use any [Command], [Client] etc annotation..so I t$$anonymous$$nk each client control each car and move it throught keyboard input (i don't know if t$$anonymous$$s is correct..or if the server should move the car and then notify the client (how?) ).

I link a video of what happens, so you have a better understand of my problem. If you need other info/screenshot of the editor, ask me!
