I think the biggest cost in this business is the human component. For that all you need to do is check the price difference between renting for a day or getting taxi for a day. Given a choice, Uber would love to be the first to have self driving cars. Once they do that their business model scales predictably with capital. Whoever gets self driving technology right, will own all transportation and logistics - which is…
But note that Uber doesn't become superprofitable from SDCs unless they're the only ones with them; otherwise, they have to cut prices in line with the other SDC-ride-hailing apps. Even under an optimistic scenario, might have a two-year SDC monopoly, after which others can offer the same product. That's still not nearly long enough to justify the valuation.
With this in mind, how does anyone else compete without burning through far more money trying to gain market share. Uber burned through the money trying to be efficient when the market was much smaller. Once the market is much much larger, any competitor will have to burn through a orders of maginitude more cash to buy market share.
There's a lot more to succeeding in this market than self driving cars.
