Interesting article about a project to map the relative merit of different modes. Even in cities with reasonably decent transit, biking and driving remain a better option.
I'd take the analysis with a big lump of salt. For example, it maps single trips from one node to another. I also don't believe it considers weather. (Do you want to ride a bike during a snowstorm? Would you take a bike or a car on a trip to the Costco off New York Avenue in Washington?)
