There were three things in Waymo's latest CPUC filing that interested me. First, through the end of August, Los Angeles still irrelevant. Over 85% of their California rides were still in SF. Second, ridership in SF doubled in 90 days without a significant expansion in either vehicles or trips per service hour, but they had the cars out on the road more hours every day. Third, the geographic concentration of their rides is extreme, with a large fraction of trips starting near either the Ferry Building or Fisherman's Wharf, which suggests that it is popular with and useful to tourists.
