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.
I think a lot of the difference between people comes down to their childhood - what they learned as default behaviour. Though obviously people can change as they grow up too, either personality wise or having health/physical reasons they either can't walk far or can't drive at all. But my point is that just because some people feel that 3 minutes is the maximum time for walking before a car should be used instead it doesn't mean that short distance is an immutable fact, and many people could get used to walking slightly further distances and discover that no only is it not the end of the world, but it's even a good way to stay or become a bit fitter and healthier!
I never drive to the store and I still wouldn't do that.
Like, a car _is_ your shopping cart you take to-and-from the grocery store. It also carries you to work and does all sorts of other things.
These "crappier than a car" solutions seem to be from people who haven't really thought this through IMO.

The solution is to have a store walking distance from the house, meaning you don't even take large amounts of groceries home. Why buy a lot of groceries when whatever you want is within walking distance?
When I visited Manila, Philippines, my life was like this. Fresh bread? Just walk to the corner store, no reason to take extra home with me because tomorrow morning it'd be baked fresh again. Why should I spend on 2 pan-de-sal (great tasting Filipino bread btw) for today-and-tomorrow, when I'm planning to walk to the city-corner again to well... do anything anyway? The bus is there, the food is there, breakfast is there, everything is there. Its less convenient to even take anything home outside of eggs or other longer-term goods.
But you need to live _much_ closer together than what Americans are used to. And there needs to be a reason to go "to the corner" (ex: to take the bus or other public transit). Etc. etc. etc. This simply doesn't work in American suburbia.
American City centers, such as New York or Washington DC seem to have figured it out in my experience. But prices for this lifestyle are higher than just buying a car and living in suburbia. So yeah, Americans recognize the value of this lifestyle (despite all of our debate and complaints). But there's not enough space/housing in cities to have enough people live a car-free lifestyle.
Aren't there shopping malls in the US longer/wider than this?
I think I walk further than that between buildings to get to the canteen at lunch time. I tell people I live "really close" to a metro station and it's 380m away.
It's not like people go to malls as frequently as they go grocery shopping, so this doesn't really imply anything. Also don't forget you're carrying potentially heavy bags. Also don't forget not everyone is a fit 30yo.
