If you mean actual taxis in San Francisco, it's not a drop in the bucket. There are 1,800 taxis and compared to 300 Waymos, and the latter have a much higher duty cycle. It's true that the number of Uber/Lyft is a lot higher, something like 40k drivers (who work a widely varying number of hours per week). Yes, the 100M miles scale is very important, because that's about how many miles humans drive until they cause a death.
