I would imagine that Uber would be investing in self driving cars. I don't think there's as much money in taxiing people around as Uber and others initially thought. Even with the taxi market being artificially constrained the number of taxi driver millionaires seems to be a little low.

At least in some countries and cities getting a taxi at the right times have been a hassle, and somewhat expensive. So even if, like Uber, you can expand the marked and steal customer from traditional taxies, how much money is there really to be made? Getting the profit that currently falls to the drivers seems like a logical next step, if they want to increase their own profit.
