This was 20-25 years ago. No Uber Cab, no Google shuttles, no e-bikes, no rental scooters, Caltrain was diesel and hadn't been renovated, and there was no real-time tracking of Muni buses' positions, so unless you were taking an express bus, you had no idea when the bus would arrive at the stop. And a large part of San Francisco's population was still poor.

There were a lot of people who didn't use a car in that context at all, but people who could mostly did.
