I've responded, but you decided to dismiss everything.

It's a fascinating psychological and sociological question: why Americans think that the only possible state of things is the current one as it exists in the US, and why they are completely incapable of imagining any ither possible solutions.

E.g. "Trains already exist almost everywhere they make sense to exist, which is apparently to funnel people back and forth in Japan and a couple of northeast US states".

Yup, country the size of US eastern seaboard with comparable population only needs to "funnel back and forth". And Northeast Corridor just apparently appeared out of nowhere because it somehow was needed exactly there, and not anywhere else in the US, and also "just to funnel people back and forth".

Unlike cars. Americans don't need any other forms of transportation because they are physically incapable of imagining other forms despite success cases existing even in the US, and proven to work even in the shittiest third-world countries.

It's not unlike talking to a brick wall.

Adieu.
