Why do Uber and Lyft have to develop their own self driving tech? If what they sell is their routing algorithm for drivers, they can simply lease self driving cars from the companies directly and run them on their network. The car companies would be happy to get a cut of the profits.
What advantage would they get by developing their own tech? They have to manufacture the cars themselves or lease the tech to other companies to cover the costs.
Uber and more so Lyft seem late to the game and Uber in particular seem to be fraught with problems and have not made the progress they hoped. So why pursue that? I understand if they started early and are making great progress. On the flip side is the tech no where near completion? Then that would make sense. But Google seems to indicate that they are very very close to launching their own taxi program.
