There's a world of difference between walking 15 minutes and driving 15 minutes, and overall having people walk usually makes for a better overall urban environment. You wouldn't want to walk along a highway, but because everyone drives in major US cities, even downtown has highway-sized roads. I'm not super for sleeping in cars, but I already pay a space tax for my living quarters to have walkability (even if I end up taking the train)
