My data point when I lived in SF is I would walk a third of a mile with two bags of groceries. But didn't really want to walk half a mile. Back when I lived in San Jose I could also walk to the store because way back in the 1940's they put a pedestrian walkway between two streets which dropped the walking distance from my house to the shopping center from half a mile to again a third of a mile. Which brings up something I think is over looked. Which is the layout of streets in post war housing tracts makes the distances you need to walk twice are far as they could be. With zoning changes, money and some eminent domain we could make things better.
