This is kind of nitpicking, but this has always been a backup plan at best for Uber. Look at their expenditures and it is clear that their strategy has never been "all in" on self-driving.

Their main plan was and basically still is a combination of driving competitors out of the market, increasing their efficiency, raising prices, and lowering payments to drivers, before the money runs out. If self-driving cars happen, it will be a tremendous boon to Uber's bottom line, but it is not a necessity.
