pushing for better transit
Eh, I'm still not sold on transit (for people). If you live in a well designed city, everything should be right there in front of you, no more than steps away. The need to move further than your feet (or wheelchair, if that's your thing) can reasonably allow is a straight up urban planning failure.
I can buy into the idea that, given our existing urban planning failures, it is better than nothing. As a bandaid, sure. But in the context of looking to build the world in which we want to live, why settle for bandaids? Why not go straight to building cities properly, thereby having no need to move people around with external propulsion at all?
Those in the rural parts are a harder problem, but it seems you think the car is still their best option. So, when does transit become useful?
Is it the freight transit infrastructure you see as needing improvement? It is true that, even with the best laid plans, we are not in a place to give that up yet. As interesting as vertical farms are, the technology just isn't there yet to supplant food grown in rural areas, never mind things like lumber and other commodities that aren't usually found in cities.
But when it comes to people, concentrating them close together is kind of a city's whole deal. Why then pretend it is a rural area that requires travel over long distances?
