I would like to see the math on that. It&#x27;s inefficient in terms of bus-miles driven, but assuming that we value people&#x27;s time, it&#x27;s not clear to me it would be inefficient in dollar terms.<p>Yes, insufficient concentration is a problem, which means that living in the suburbs would still be more expensive in transport costs. I still expect (or perhaps hope) that we&#x27;d see a contraction back to more dense urban cores. But automated transportation could provide a bridge between the suburban model and whatever comes after.
