Little maglev pods, man. One seater (stander? layer?). They can string together in a train or go off individually. Switching stations no wider than three or four lanes, underground. You plug in your destination and hop in. Tubes small enough that they can also extend above ground and integrate into other transport. Would probably make people too claustrophobic to ever catch on though. If the feds could be like "yeah it’s small, but we’ll dig a tunnel right to your road and you can blast around safely in basically a straight line to wherever you want to go in a tiny fraction of the time driving would take, it would catch on.

Yeah your idea works, too. The last mile is the hard part. I agree we need a ten minute walk to a bus to make them useful. In America I don’t know how that would be realistic for most places. I feel like most of America landwise, you’re lucky if its a ten minute walk to the next house. So unless the busses are going up and down every road, that means at a minimum need an ebike maybe, but more likely just a car.

In my maglev solution, which I am making up as I go along, the switching and intersections and other key infrastructure for my maglevs are in large, modular blocks that get buried in a giant rectangle hole, maybe the size of a kids football field, and then we build a park and station right on top of it. The tubes can then go basically anywhere, connecting the modular blocks together. The roads are antiquated. The future of travel is sub terranean. Hopefully we don’t also have to live down there.
