True, but you probably wouldn't rent a robotaxi if it's $1/mile. That would cost you something like $2k. This is why I can't see robotaxi replace most privately held cars unless it's much cheaper.
Say you need to make a 500 mile round trip over two days?. If you rent a car today you could probably do that for $200 including gas. That's something like $0.4/miles. And most people won't give up their private car even knowing they can do this.
The cost per mile need to go way down from that discussed $1/mile for 'most' people that have a need for a private car today to give it up.
I don't see any way that robotaxi cost / mile doesn't go down, after some initial golden period where the competition is made up of taxis, uber, and Lyft as currently constituted. Once there are enough robo-taxis, the cost / mile will come down to more typical transportation margins, whatever that cost/mile is. It might be more like a flat cost to come get you, and then a really low cost/mile (like .10 or something).
The thing about transportation is that it's such a big industry with so many participants, the margin in the industry invariable drives down to something pretty thin. Even space transport will eventually (though maybe not in the next few decades) be driven down to significantly lower margins (even if that's hard to see today).
The way Buffett put this years back in one of his Letters to Shareholders - there are some technology advances where some of the benefits stick to the fingers of the business(es) implementing the technology. The IT industry and productivity benefits it brings is one example that comes to mind.
Other technology advances see their benefits flow through almost completely to consumers. Good for consumers, but not as good for the businesses implementing the technologies. HIs example of that was a factory in the clothing industry - a new loom or something came along that would 10x their output (or whatever) and they were looking for some money to invest. His response was more or less - you better hope it isn't that good, because the capital investment won't be recovered and the price of clothing is about to go down. Good for consumers, but bad for that business (more cost for the loom, but no pricing power to recover that cost).
The way I see it, bulk transportation of anything (people, goods) tends towards pretty thin margins.
There is no way that there is a sustainable annual payback business in robotaxis that goes on and on, for years or decades (unless those robotaxis remain exceedingly rare).
Just like semis that lower fuel cost/mile by .30 won't lead to a .30/mile incremental profit for the buyers. In the very early days they will, but once electric semis are reasonably ubiquitous, all of us consumers can look forward to whatever a .30/mile cost reduction translates to on our Amazon etc.. orders.
