Trains are a tough sell, at least in the western US. So much wide open space, trains are slow, high speed trains too expensive to justify given the sparse population.

I remember once doing the math and finding that there are many times when our local light rail is less efficient than just putting four people in a sedan. When the train is full, though, it's unbeatable.

EVs throw another wrench into that math since they're so much more efficient than ICEVs.

The sparse population argument seems kind of BS

Switzerland has a low population and is covered in trains

> low population

These are not the same thing. Switzerland has a pretty dense population. The section with low population is the Alps, where you're not going to put trains anyway.

Most people that live in remote areas have cars anyway, since sometimes busses only run twice a day. It's a tricky problem to measure "access to public transit".

(The BFS is an amazing source for information, they publish all kinds of statistics)

Switzerland has a similar number of people the bay area, 7-8 million, and is twice as large. So it stands to reason the bay area could have a system as large, useful, and as efficient as Switzerland if not better given it has the amount of same people in a smaller less mountainous area.

You just confused the Bay Area with “the western US”.

How so?

Population Bay Area 7.7 million

Population of Switzerland: 8.6 million

You picked a tiny subsection of the western US to be representative of it.

See if your comparisons make any sense looking around Fresno and Bakersfield (which is still generous). Then do the area around Elko Nevada.

Not to mention, eventually the whole grid should be mostly renewable rendering questions of efficiency more-or-less moot.
