This is a company that had enough spare parts laying around that they could build an entirely new assembly line out of them[1]. They are also notorious for making customers wait months for replacement parts [2]. Tesla has a lot of successes and a lot of valuable IP that competitors might want to steal. Logistics might be the last thing on my list of things worth stealing. Although I guess that doesn't necessarily mean that no one would try.
