As somebody who's lived in both Amsterdam and the Bay Area, the list of things that Bay Area car advocates say are impossible that I've seen work with my own eyes is endless.
I mean, when I’ve visited San Francisco, it seems to have supermarkets all over the place too (albeit rather expensive, not-very-good ones), so they even have a local model.
When I visited SF I found that to be the case in some neighbourhoods, but in others like... everything West of the downtown, e.g. towards Golden Gate Park, Richmond, Sunset, Twin Peaks, etc. was extremely barren from anything other than single family houses, with the occasional street with restaurants and shops.
