Hmm, seems to me that comparing the ratio of "place" to "non-place" in newer vs. older cities is misleading. Those ratios are all about transportation. Many U.S. cities were founded and designed around wheeled transportation from the beginning, whereas many, if not most, European cities were founded at a time when foot and horse traffic was the norm. If the way that people get around changes then the cities will follow along over time. Personally I think that the conversion to autonomous vehicles will have a tremendous impact on vehicle size, road density, road layout, etc. It will enable cities to be very different from the way they are now.
