The article mentions that his spread out, one-acre-per-person city "would be connected by a complex design of streets and highways."
Is anyone familiar with his highway plan? My impression of city planning is that roads are the hard, boring part, so I'm curious if Wright's roads were just a thing he drew between his beautifully arranged buildings and parks, or if he had an actual plan for how to move people efficiently around his cities.
Saying "everyone should live close to their workplace" only works if you have a single, mega-office/industrial park, with all of the housing arranged tightly around it. Once you have two places people can work, changing jobs requires people to change houses, and only people who work together can live together. So in practice you need to have a transportation system that allows everyone in the city to commute between work and home in a short amount of time during a small window of time in the morning and afternoon.
Sitting in traffic in a beautifully designed city does not sound particularly more fun than sitting in traffic in a poorly designed city.
