With subways like BART allowing bicycles, going around traffic jams and being economical and somewhat social, basically cars, taxis/Uber and public transit are fundamentally different services that strongly overlap.
Which means no one is going to be happy eliminating any of these and that makes it even harder for any self-driving taxi system since it would have to indefinitely navigate human filled roads and would add-to, not replace, all the traffic that exists now, threatening considerable congestion.
