There are a couple of other important factors: one is safety. Waymos observe traffic laws and safety rules. With enough Waymo on the road, everyone else will be forced to obey speed limits. As a cyclist, I welcomed the day when Waymo waits to pass me rather than a human driver who will get impatient and do a close pass. The reason I say Waymo specifically is that I don't think it's well appreciated the tech advantage Waymo has by using Google's unequalled geospatial data. Elon keeps claiming that Teslas will do the same thing much cheaper and everywhere, but there's no actual evidence that that is possible. Grinding out larger and larger service areas in more cities is likely to be the way automated rides expand for the next several years.
