I think that's a fair point. I suspect Tesla will end up being very much like Amazon: a company that ships physical goods but acts like a tech company. That is, they'll operate on razor-thin margins and dump every penny of profit into R&D in perpetuity. That will probably give them a leg up on companies that pay dividends, at least in the short-medium term. Ultimately, though, they run the "risk" of being Apple: a company that has to spend inordinate sums on R&D in order to gain a 1- or 2-year window of exclusivity before the competition commoditizes their product.
