Weren’t they trying to do their own self-driving thing?
I think this is partly a problem with companies that have had heavy investment. Uber’s value isn’t based on what they are doing, it is based on the idea that they are going to render ideas like owning your own car or taking public transit obsolete (I mean that’s an exaggeration but less of one than it ought to be).
AFAIK they gave up on doing self-driving themselves a while ago. I'm sure they are still hoping to be able to get rid of human drivers somehow.
They shut it down after they killed a pedestrian. (They also got sued by Waymo for illegally acquiring trade secrets, and settled.)
