Is that why the streets are empty and you can always find a parking space in London? How about downtown Shanghai? Or Rome? Or the suburbs of Guadalajara? This qualifies as some of the rest of the world and all of the places mentioned are traffic nightmares. It must be all of the walkers clogging up the roads.

As far as the rest of the world loving it, that's ridiculous. The mom in rural Kenya walking miles each day for water.. I bet she'd love a car. When you have to get to a meeting and its 40C outside, I'm sure a brisk walk would be just adorable.

Not everyone can afford to live within walking distance.
