> So you get this ridiculous situation where US cities can point to all these shiny new bus lines and bike lanes as "progress", but absolutely no one can afford the housing needed to use any of that, so on a CO2-per-person basis, we've regressed significantly. And 1990's era cities with it's freeways and parking were often better for the environment on a CO2-per-person basis than 2019's cities are today that lack those. There's no way this is true. Housing density has increased within cities themselves. Generally things have also become more CO2 efficient within the cities as well. More people live in cities than 20 years ago. If someone in the suburbs drives, it's the same (or less with modern cars). If they use transit, it's less. If they move out of the suburbs or stop commuting, it's also less. Where does the CO2 increase come from? It's also important to remember that these trends vary vastly depending on the city you talk about. High density cities with good existing public transit infrastructure have very much succeeded and improved public transit, not destroyed it. LA is very much not a good example due to the sprawling nature. I lived in LA for 6 months and would not call it a city but rather 13 connected suburbs. A bus there is indeed a failed project. Heck, even the Expo line they just built to connect the west side is a lot of travel time and not much coverage.
