The low/medium speed maglevs also seem interesting:

A 70-100 mph maglev would be useful in a few large cities.
This is rather obvious and has always been a major advantage of rail. The problem is the capital costs and real estate requirements of building the rail lines, especially when locations are far apart and there's already existing infrastructure that needs attention.
As for "far apart" this seems irrelevant. Ohio has a greater population density than does Spain, but Columbus, Ohio's principal city, hasn't had a passenger train in 42 years while Cordoba, with half the population, enjoys ten trains per hour service including a high-speed train to Sevilla, Madrid, and Malaga. Anybody could build a Columbus-Dayton-Indianapolis high-speed rail line but we lack the will to do it.

I don't think anyone is "discovering" this. The US has prioritized other modes of transport because the US had priorities beyond "how clean it is".
Such as?
There's some famous interview - can't remember with who - about how at the time getting a car gave incredible freedom nobody had experienced before. It was a big part of how people saw the American dream in the last century, before the impact was understood.

Because if a product doesn't make boatloads of money for an oligarch in a big city somewhere, that product doesn't deserve to exist.

Individual independence and convenience were a goal in American culture the middle of the 20th century, until the externalities of that were understand.

Cycling is cleaner than any of them. So what?
They’re measuring energy per passenger/km but I think ignoring the cost of building the infrastructure (the “get data” link is down). For roads and railways infrastructure investments are huge, both initial construction and then maintenance. Not only in dollars, in CO2 as well.
