Can’t be that bad in SF. I first lived in SV then in Greater NY Area, but not in the cities. In either case there’s like one or two small grocery stores within walking distance, I can’t even do proper shopping without a car, unless I’m willing to bike for forty minutes or more in the two-feet-wide bike lanes (sometimes nonexistent) without any separation from motor traffic. (And in the latter area, should I choose to bike, I would be the only cyclist in miles.)
