How does Uber come out top in that? Surely that self driving software/car makers take the rewards. Uber is just a booking platform on top. Why would Google (with Waymo) allow Uber to book their cars, or Tesla to book their cars? They'd surely set up their own competing service to Uber and force them out of the market within months (as the prices would be so much lower).

I'd imagine the software licensing of self driving cars would be so that when you bought a self driving GM/Ford/whatever that is only for personal use and using it for taxi rides would be against the ToS. Which they could quickly catch people out on, and maybe a "taxi" version of the car costs $xxx/month more.

Unless you are suggesting that Uber actually wins the race to self driving, which I really can't see happening. Do they even have a program anymore?
