This is a superb post with lots of info and analysis: bravo! And thanks. I will quibble a bit with the industry's assumption that once the cost/mile lines cross massive adoption will take off. (We said the same thing about TCO for EV versus ICE, remember?) I like robotaxis, I use them whenever I can, and I think their usage will soar. But I am not sure that the rosiest adoption scenarios will come to pass, because POINT TO POINT COST IS NOT THE ONLY THING THAT MATTERS TO CUSTOMERS. (If it were, no one would ever buy a new car in fact: a clean used Accord would beat any new car in cost/mile!) There are so many other sources of value in using your own car versus a rental/taxi/human-Uber/robotaxi: More CONVENIENT to jump in your own conveyance and go where you want when you want. We value our time and our capriciousness. Who wants to always be poking a phone to see where the darn cab is? COMFORT: You can set up your car to cater to your tastes, interests, needs and comfort. STUFF. Many of us treat our car as a backpack, full of stuff available to meet occasional needs: golf clubs, change of clothes for the gym, car seat for the kid. INDIVIDUALIZATION: Having your car as a statement of what kind of person you are can be a significant share of its value. Why does anyone ever buy a sports car? Arriving in an Uber says nothing. CONTROL: You can fix your costs of transportation with your own vehicle. Once I give up my own car, I am at the mercy of whatever prices the ridehail or robotaxi company sets. I can defer maintenance if I want, take the car to Cousin Fred for cheap work the OEM would never approve of. HEALTH: I can keep my car clean – or not, as I want, but I know who’s been in it: me. Do I want every trip I take to be with germs other riders have left behind? Remember Covid? RANGE: Ridehail and robotaxi economics depend on population density, reducing service and increasing price for rural trips. I want to be able to go anywhere at any time, with low marginal cost. ..... To me what this all says (plus falling robotaxi costs) is: PERSONALLY-OWNED AV. The AV tech is so great, and is getting cheaper, why not own the darn thing, versus have to summon-and-pay over and over? Put the kids' car seats in the back and leave 'em there. Leave the groceries in the trunk while you grab a ramen bowl: no need to summon a robotaxi twice. Etc. The future I see is: "Cadillac... plus Waymo Inside©" (grin) If cost/mile rules, why does ANYONE in Manhattan own a car? Because 25% of households there DO. My view: we find a new equilibrium: long trips (airplane), micro-trips (bike and feet (Shoeber)), medium unstructured trips (rental car), simple point-to-point trips (human or robo-ridehail), complex errand trips (owned car, AV or not AV). Etc. Silicon Valley always looks myopically at EFFICIENCY (doing things right) and not at EFFECTIVENESS (doing the right things). End of Rant!

Tesla is NOT doing AV in the SF Bay Area yet, nor even in Austin. Makes me seriously doubt any of the data in this post.
