The top number may not mean much, but when your company is losing multi-BILLION dollars a year, then people care. Unless eventually Google sell Waymo to the government who can use tax payer's dollar to run a loss like public transportation, they have to show a path to profitability. Too many companies tries to fly before they can walk. In the EV industry we see Lucid and Rivian being prime examples, losing magnitude of money more than Tesla in the same given execution time line.
Waymo and Cruise are in the same boat. The market is not yet READY for robotaxies, and their products are not yet ready for the masses(due to all the limitations). Cruise gave a total of 2,783 rides per quarter from 300 deployed cars. This is 30 rides per day from 300 cars sitting dormant. This mean 90% of their fully functioning robotaxies are giving out ZERO rides per day! This number needs to X100 just for the demand to be sustainable as a business...however all of these companies continue to expand their business which increases cost. Fly before they can walk.
Tesla is learning how to crawl...it's slow and painful, but it wouldn't tank a business.
