I would love to see more and more car free cities and other urban sprawling, but I have to say, this centralized business model where this developer is providing all the amenities, passes for the near by rail, paying rent to this developer, basically everything goes through them, they even had an app for the community, this is not a viable solution. What happens when this company is not able to sustain the spending or goes bankrupt, or worse sells majority share to an equity company. A decentralized model that goes through local government is a better option and not through for profit company. Even better option is to start from city center not a separate community on the edge of the city. I know what I'm saying sounds impossible in America, and with lobbying buy auto makers and other large corporate overlords, it probably is impossible. Social change can bring about the difference.
