Thing is, Tesla will still need authorized repair centers in may smaller communities. They're not going to own repair shops worldwide.

Example with a different product: a friend of mine is from St. Lucia (the island). Closest Apple (owed) store is an hour's flight away in Port of Spain, Trinidad. Local "authorized" Apple stores are somewhat incompetent, so her mom brought her MBA laptop to NYC for repair when she visited.

If Apple doesn't do it with a computer store, Tesla won't do it worldwide with car dealerships, which have a higher startup cost than a storefront.
