    PutPlayerInVehicle( playerid, gVehicle[ playerid ], 0 );

    SetVehicleZAngle( gVehicle[ playerid ], angle ); // Same for this too!

Note; you should get the player state and if the old_state was driver and the new_state on foot, you should put the player in the car as a driver, because it will be a bit fail!
