What's your basis for the conclusion that it's "shit tech"? Have you tried riding in one? I've found it to be an incredible product, like using the iPhone for the first time. There's one lady who's posted a lot of YouTube videos of Waymo. She's taken over 500 rides. So there are clearly people who get a lot of value out of it.
Also, no one is making money off self driving tech any time soon, people have been working on it for more than a decade and it costs billions. It might be another decade before it is profitable.
Then there is this lady who highlights fundamental issues with the way these vehicles operate. This isn't a teething problem that will be resolved with an OTA - it shows the tech isn't ready to be used on public streets and probably shouldn't ever be.
