The actual point is hidden midway through:
'“When you go to justify a major investment for pedestrians and bikes, it gets really hard because you don’t have good data,” Loewenherz said.'<p>...as opposed to a major investment for cars, which is just common sense, right? I have yet to see such an investment backed with "good data" - just handwaving and "more motorways is good, because it's good, and <i>that's</i> because it's good."
