sadly, tesla does not have motivation to spend money on adding new service centers.
in areas of the country where teslas are common, they sell themselves. people find out, after they buy, and then its too late. the sale is made and after that, the other side of tesla is cash-challenged to keep up.
in areas of the world where they are less common, only early adopters will buy them, and again, they'll typically put up with a lot more than the usual consumer will.
until tesla sees that it costs them real sales, they have no money-based reason to add more service centers. I kind of see their point, but its really short-term thinking and it will bite them (it already is, imho).
tesla just needs better BALANCE. its not all about sales, dammit. please, stop the push for sales, let the other groups catch up for, say, the next 3 months. (yeah, I'm dreaming).
