>Before Uber, cabs (in SF) refused to take credit cards, regularly didn’t show up when pre booked In September 2005 I spent 20 minutes on a Sunday afternoon trying to get a cab at 19th and Judah before giving up and taking a Muni. (For those unfamiliar with San Francisco, 19th is the main north-south route through the city, so is very very busy at all times.) This is the sort of problem that car sharing has completely solved.
