The solution looks good. But the remaining problem is density. The higher the density the easier is to provide services for the population. New York, Tokyo, Paris, etc, have several store tall buildings with people living in apartments. For what I see these new cities are more similar to Los Angeles or Mexico City than anything else. Single-family homes spread all over the place without access to trains or subways. I have lived all my life in apartments. So, for me, it feels normal and it is very practical. I guess that if you are used to single-family homes that is a difficult step to make.
