The grocery store example is very helpful to illustrate how its not just the quality, safety, and practicality (e.g. time) of the walk that leads to most Americans driving- there is also the fact that the whole process and experience is predicated on the expectation that you will have a personal car. Specifically: In the parts of W. Europe I have visited I observed mostly small grocery stores (esp in towns and cities) that folks visit daily or nearly so for food. People may stop on thei walk home to get dinner items each night! Contrast that with the U.S., where you are more likely to encounter a large grocery store- except perhaps in the densest inner city (but then maybe no grocery store at all, which is another story)- where people visit once a week or so. When people go to the grocery store, they stock up. Stores are optimized for buying multiple (more than you can carry at once) bags of groceries, which you then necessarily would load into your car and drive home. Most folks would not willingly opt to take a long risky walk through unpleasant surroundings, traverse a giant parking lot not designed for walkers, then have to march through a large grocery store for many minutes to leave with just what one could carry. Sure, folks could bring a personal hand trolley or something but this really does not address other underlying problem. So, in the case of grocery stores the basic culture of shopping at a very large center less frequently would also have to shift for people to leave their cars. And, I would argue, so it goes with many things. Shifts to a more pedestrian-oriented culture and environment may happen with time or in certain areas, but I don't think it would be simple, quick, or widespread any time soon in the U.S. for reasons that go beyond sidewalks.
