Felicia Panfil I know your title is car-free, but why would you exclude all the new electric vehicles including automobiles and delivery vehicles? Logistically any city needs an enormous infrastructure just for food which you can't pipe in nor use only pushcarts. Most public transportation is ill-equipped to deliver goods, but perhaps that could be part of your contribution. Certainly, some food production in the metropolis is a concept to take into consideration. In addition, the is the almost sci-fi idea of Elon Musk's tunnels for electric vehicles because building underground has become so cheap. I await your plans for a city of the future with impatience.
