The problems with getting public infrastructure projects done in time or at all are political, not technical.
There typically are no technical solutions to rhose.

It's not needed now, but we think that it will be needed in the future
It's needed now, but we don't know if we will use it in the future
How MUCH will it be needed in the future
Will there be a future technology that makes this investment unnecessary, or even obselete before the project ever completes
For the latter, a big argument of "No need to invest in commuter trains" argument was "self driving cars are 'just around the corner' and they will make mass transit a quaint thing of the past" was used to deny investment in trains.
People don’t want to invest in trains because Americans don’t like trains. We have only one real city, and that city’s population consistently has net domestic outmigration. The city’s population is kept stable by a steady supply of international migrants: https://www.cityandstateny.com/media/ckeditor-uploads/2025/0....
Most Americans don’t want to commute sitting next to strangers. It’s not complicated.
They use them heavily when they're available. The NYC subway is very popular and successful, and many see it as a selling point of the city.

I never hear city residents talk about 'strangers'. Interacting with others is a pleasure of cities, in fact - it's energizing, it builds social trust. We're social animals. I've never gotten on public transit, or walked down a busy sidewalk, and thought about 'strangers'. Most of those people are pretty sociable.
Does everything work perfectly all the time? No, not in anything. If you cross the street, maybe someone will drive right into you. But I cross streets without a problem.
Seriously, what's the big deal? People are looking to confirm all the anti-city hate. Maybe if these people make you uncomfortable, the lack of trust is in the mirror.
NYC has only 2.5% of the U.S. population and even then it has net domestic outmigration (meaning more people move out every year than move in). The city would be shrinking if it wasn’t for international immigrants, who don’t come to the city for the public transit, but rather the welfare system and ethnic social networks.
I think your numbers are wrong: the city's foreign born population has been stable for at least 15 years[1]. We're not even at historic highs; those were before WWI.

This statement doesn't contradict the one about international immigrants keeping the city from shrinking. It is easy to imagine how immigrants come to NY, give birth to natural born Americans, who then move out of the city. This process can come to some kind of a dynamic equilibrium with a stable population of foreign born people.
People use the trains in places like Chicago and NYC not simply because they are available but because owning and driving a car in the city center is very expensive and impractical for most people.
Anywhere less dense, people prefer to drive their own cars.
Did you hear about the other other lawsuit about people burning to death in their cybertruck? Should we compare horrific deaths per passenger? Per mile traveled?
Not that they can't, but they won't.
