I hadn't thought about it like this, but I think I want the grassroots version of the PR campaign. Society was finally able to rein in smoking when we collectively realized how dangerous secondhand smoke is. People who smoked indoors and exposed loved ones to an early death weren't bad people, but creating societal pressure to feel bad about doing that has saved a lot of lives.

You are more likely to kill someone driving your huge SUV than you are taking a Waymo. Driving your own car certainly doesn't make you a bad person, but I hope self-driving cars will be ubiquitous and safe in the future. When that happens, choosing to drive yourself will be a selfish act, just like exposing people to secondhand smoke is now.

At a systems level, transportation is something we have to be very, very careful about, because if you get it wrong, you start excluding entire groups of people from being a functional part of your society just because they are different from you in where and how they live.

"When that happens, choosing to drive yourself will be a selfish act, just like exposing people to secondhand smoke is now." Really? I drive on logging roads a few times a month to get to some property. This is pretty sketchy even in good conditions and there's always the chance of getting stuck and having to hike a mile or two the rest of the way up to go get the tractor and sort it out. I'm probably not buying a self-driving car any time soon, if ever.

Now, is having self driving taxis a fantastic idea in a very dense city? Of course. There's huge benefits in keeping the average car as safe, efficient in both energy and pollution, and highly utilized as possible. Are these also a good retrofit to dense-ish suburbs where a bus/rail network isn't quite enough (and the costs to build it in already-developed land are unpalatable)? Also yes. But that's not ubiquitous, that's just part of a larger system that needs to be able to serve all users.

And if your point is that "move out of the mountains and into a city because that's the less-selfish option"... that's a certain kind of political statement, I guess.
