Well this doesn’t jibe with the current reality that Waymo is teaming with Uber right now. To make Waymo economically viable, it needs to be almost 100% utilized.
Also because people hate using multiple apps, you need an “aggregator” (see Stratechery). If I go to a city and I need a ride from
the airport, my default is going to be to open Uber - not to say “oh yeah, Waymo is available when I fly into ATL but not when I fly into JFK”. Uber was even available when I flew into QXP from San Jose Costa Rica (https://en.m.wikipedia.org/wiki/Quepos_La_Managua_Airport).
Also many businesses have “Uber for Business” where business travelers can automatically get their Uber rides charged to the company instead of having to do reimbursements. How many companies are going to establish relations with Waymo to and tell their sales people/consultants - “use the Waymo app in cities where it is available otherwise use Uber”?
Just like I’m not going to open some taxi app when I fly into DCA. But I will open the Uber app and choose a taxi (with the standard taxi regulations) if it is more convenient.
Business travellers is a lot more lucrative for companies than consumers.
But getting back to Waymo and utilization, if you know you need both enough capicity to handle peak utilization and want to have capacity to handle steady state, you are going to have Waymo as a baseline and people that will come out when they think it is worth it based on current surge pricing.
Having enough Waymo cars available to handle peak capacity would be about as dumb as Intuit having enough server capacity in a Colo to handle tax season instead of using AWS and autoscaling.
Uber is also managing maintenance for Waymo in the cities it is available.
