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.
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.
It's not that people refuse to ride busses. In most places in the US this is either a non-existent or extremely impractical option. It's just reality.
And remember, the alternative is even worse: buses.
