What exactly is your point? This seems like a bizarre take on a massive city having good transit and it’s not like it’s some global oddity without parallel. Cars don’t scale and they have massive negative impacts for cities (health & safety, pollution, noise, inefficient use of space, etc.), and it’s not like there’s some unique trait which makes people recognize that.

And efficient trains can't exist in multi cultural societies ? Is that what you're trying to say ?

You’re a monoculture

There is no possible good-faith way to draw that conclusion from a statement someone was making about the rail system in the world's largest urban area.
