The rare earth dependency on China is very much overblown. The U.S. has very significant natural reserves of rare earth minerals. The problem is the same with all mining - it's uneconomic to mine minerals in the U.S. because the job of "miner" is unattractive to Americans (both the laborers and the governments that sign environmental permits) when there are cleaner, safer, and more highly paid jobs available.

They're also just as much of a CO2 solution as electric trains are, i.e. it depends on the fuel source for the local electric grid (which today is overwhelmingly solar in most of the places where EVs are popular).

We're dependent on processing and refining, not the minerals themselves. Takes, from what I understand, 10-15 years to stand up that capability.

Overall EVs are great and all and that's what I have, but they're not addressing the underlying concerns and sticking with car-only or car-based infrastructure whether that's ICE or EV is a losing proposition.

No, you need fewer electric trains to move much more people plus you don't replace the trains as often, &c, and then add in all the miles and miles of paved roads you need, parking lots, you name it. There's no way around this, if you care about the environment or care about human wellbeing you have to move away from car-only infrastructure like the US has and move toward more European models. And no, the geography isn't a challenge, most people live in urban areas in the United States, China is big too, and so forth.
