How autonomous is the service in San Jose then? Do you mean to say that you have cars without drivers that serve ride after ride and come home to charge? If so I'm far behind the curve.
As a real-world example: we have a couple who uses our self-driving taxi service multiple times a day every day (The Grims), and their rides are ~95+% autonomous.
I remember how voice to text got to 95% in the nineties. It's used for a lot of things these days, still not for safety-critical tasks.
A long way to go for sure, but having been at this just less than a year, we're feeling good!
