Now you can fix cars then why not do that you could attach one machine to another or make a rope so you can tow the car and clung to the back and front.
They sort of already have implemented this into the game. Not for all vehicles, but for vehicles with tow hitches, you can definitely pull them. As for just having ropes hanging in between cars pulling, I am not quite sure why you would need this, but I guess we could find some use for it.
