Uber is basically a walking dead company. At least with this business model it just can not justify the valuation. Hence, it just can not go public and needs to continue raising more money to keep its market share. Unit economics doesn't work—this is Uber's broken moat. In the cities where it works, there are cheaper competitors and Uber struggle to become a significant player. In my city (Kyiv, Ukraine) Uber was introduced a year ago. I used it only while it offered promotional price. Now every other local ride service is cheaper than Uber and has mobile app—sometimes even better than Uber's. Yes, Uber made these services to improve, but now they are all better that Uber in terms of prices of rides, especially in surge periods. Uber with this model could survive only with: 1/ Autonomous cars to cut costs on drivers and 2/ Controlling the whole driverless platform in every city. And this is not happening since to control significant portion of driverless cars one need to control the whole driverless tech stack. It will be pretty hard to aggregate in one service different co's driverless tech with different specifics. That's what Tesla does. I guess later when driverless will become growing en mass, Tesla will start own ride service, and letting own car for the a ride service will be opportunity to reimburse car purchase. It is then that Tesla will start licensing driverless tech to other manufacturers, including sensors configuration and centralised trained AI cloud with driving skills on different roads, and give opportunity to join Tesla's own ride on demand network. It will be a car selling point: "buy a car with Tesla driverless tech and let it for rides via Tesla's network to cover payments for your car". So, it's rather hard for Uber to use advantages of driverless unless Uber builds own full stack and is the first on the roads with it + starts licensing it to car manufacturers for their cars to join Uber network.
