The conclusion reached by one of the researches behind this post, which ranks the walkability of 30 major US cities? Finally, Seattle, some music for my ears:

Top-ranked walkable urban places are witnessing the end of sprawl. This is a major change in the way we build the country.

One: There is no going back to “drivable sub-urban” Two: The researchers punished Chicago because it's centralizing and disconnected from its suburb. Yes, punished the city for doing the right thing. So, the rankings are not anywhere near perfect.
