Especially considering the OEMs advantage when it comes to vehicle pricing, maintenance cost etc. Uber seems like an odd investment. Waymo seems to have the advantage when it comes to self-driving tech, although its currently only tested under ideal conditions. And they have partnerships with plenty of OEMs like Fiat Chrysler.

If AVs become a reality, cost and therefore the pricing for the consumer appears to be the only thing that will matter for the success of the app.
