Uber turning into the taxi network for AV startups is probably the right move now that they don't have their own AVs. The driver/rider network is something they spent a decade+ building out & will be insanely hard for companies other than Waymo & Tesla to bootstrap from zero. Meanwhile, Uber can help all of these new AV startups monetize while collecting a cut. This fixes some of their economic problems, at which point they can eventually start work on their own AV program again.
