> Chicago

Some individual portions of Chicago are very walkable. Likewise with some small bits of San Diego, though you are right, not as good as European cities.

I don't know about European cities, but it's generally easier to walk around the San Diego Gaslamp Quarter than it is to drive.

Gaslamp is a tourist area, you wouldn’t want to live there, there isn’t much around. It used to be really dodgy, no one sensible would go there, but they rehabilitated it to a significant extent. Unfortunately, it is mostly only frequented by 20-somethings getting drunk at the myriad bars and tourists.

I was there two weeks ago. It’s pretty much one street with a dozens of bars. Quite empty during the week.
