I'm curious about how much time skillful, trained, smart people need to realize that collective transit (improperly named public, since it's essentially all private tapping public fund plus tickets and co from the merchandise they carry) are just speculation, practically unsustainable and dollar green, definitively not grass green.<p>Downvotes probably will be the answer.<p>Ladies and gentleman's mass transport works, it efficient and effective, where there are enough people who want to go from A to B, let's say for the purpose it was born, bring workers back and forth slums/factory. It can't be generalized. There are countless A and B 24/7/365 we simply can't much most of them, yes, we can match some, but needing anyway private transports aside, making the overall design inefficient because or you keep moving nearly empty, wasting much resources, or you keep under-utilized transport means en masse, again wasting much resources.<p>The city is the topmost of inefficiency model with their offices and high rise condos where people use both for less than 12h/day commuting between them just to be exposed to physical ads (shop windows), in the past was needed because we haven't efficient enough transportation, TLCs and ITs, meaning we need paper and being at short range. Not the costly tradeoff it's simply too expensive and not anymore needed anyway, except for finance capitalism who need that scale to profit from poor (impoverished) masses who own anything.<p>Try to imaging how NY can go green new deal. Try to estimate the natural resource costs and a hyper-generic outline of how to make it real. Now try to estimate the natural resources needed by a spread society of small buildings, properly using current tech, desktop-centric instead of mobile+cloud for IT. If you do such game you'll discover that modern smart-city narrative is the old Fordlandia one, a fascist distopic society who can't not only work but even being built with Earth resources. The ruling class today is a timocracy, so finance, so they need that model at all costs, but the society need to avoid it at all cost.
