Yeah, all the people who refuse to ride busses to the point they're willing to spend many many thousands of dollars on their own cars are just yearning to carpool in a much more compact vehicle than a bus.
I know it's not popular in some circles to say it, but people (not just evil, rich racists) dislike riding the bus because of homeless people and other people who have little reason (or ability) to conform to social norms. I only saw one a couple altercations on the bus in my years riding it in Austin, but that's enough to get a lot of people to decide it's not worth it, especially women or people with kids.
We're not willing to enforce basic safety on buses, let alone other norms. If Waymo is willing to do that, that will make it available to many more people. Even just not having to wait at the bus stop before sunrise can be a game changer.
