The cars will certainly be designed for robo-cleaning by the time we have self-driving fleets. In a free market with free choice, people will obviously pick the more hygienic fleet (which I don’t believe will cost much more, controlling for other factors).

The airline industry doesn’t work very well as an analogy. It’s not a completely free market, and costs are so high that it’s genuinely hard for airlines to provide a better experience without charging a lot.
