Seems overly reductive, both supply and demand will determine what happens. So far demand for Waymos seem fine, they can stimulate it way further by lowering the prices. The problem is on the supply side, specifically unit price economics. Intervention per mile is just one part that goes into profitability and I doubt it's biggest one. I would estimate the costs to be in this order - vehicle cost, maintenance (and vehicle longevity), human intervention, charging, fleet management (cleaning, etc), and regulatory environment.

In particular, Jaguar Waymos are over 150k a pop. It seems far fetched that any of them will make ever break even. New generation is reportedly $75k per vehicle which is significantly better. I could not find any data for Zoox vehicle cost, but given how few of them there are it's a non-player.

Finally the elephant in the room. Outside of camera vs lidar holy war, Tesla seems well positioned to dominate supply side of the equation if the demand shows up. Robotaxis are reportedly under $35k, they own the factories and know how to build more, they also own the maintenance side.
