The economics still don't work. It becomes a "public work" project instead of a self-sustained business. If the car ended up being much more expensive to purchase and operate, like it is in countries mentioned that are doing so well in rail, then more Americans would ride them. Once you have a sufficient amount of usage, then it would lead to more high speed rails being developed.
I wrote this up a few days ago for another HN post about the economics between Colorado Springs and Denver (I use to live in both, the springs for longer). It's about 21% of springs residents work in Denver. It's a ~60mile commute. There was the choice between widening the interstate by an extra lane ($350 mil) or make a rail for however many billions. Going by that second line they gave a price tag on, €3.4 billion for 182km, that's about $3.8 billion for 113 miles. About $30million a mile. That's a $1.8 billion price tag for one USA area that could theoretically use it. If you go just the shortest distance between the springs and Denver considered the "city limits" of either. Not center to center. Just the closest outskirts.
So you tell me, what would a politician prefer to convince people on a tax hike? $350mil for more roads that a majority of the people would more than likely use? Or $1.8bil for something that SOME people MAY use.
Let's ignore worker costs to operate the trains, rails, ticketing, security, etc. Also, let's ignore fuel/electricity costs. Also, let's ignore insurance. Oh, and preventive maintenance, upkeep and the sort. What sort of prices do they have to charge for about 57,000 to use the commuter to make it economically viable for the city(s)? Let's take $10 a day. 57k x $10 x 20work days a month(avg) x 12 = $136.8mil. It'd take 10+ years for it to break even. If everyone volunteers to work there and fuel was free. And no accidents. And no need to fix things. No paid janitors either. Or flushing toilets. All that costs more money.
If you price it $10 or more a day, why would anyone logically change over from their car already? It costs $8-$12 in fuel a day to make a round trip in a car anyways. Plus you don't have to wake up any sooner to catch the right time train to get to work at a decent time. Plus, a majority of the vehicles heading north to Denver (I use to make this trip relatively often by the way) is filled with plumbers, carpenters, electrical workers, landscapers and the sort. They have their own trucks and vans to carry tools and materials. None of which you can take on a train for a practical expense or in practical effort.
The economics for a high speed rail doesn't make sense with the cost in the USA. Fantastic they work well elsewhere. Great for them and their not car dependent society. They don't work out well here. It's time to mature and grow up to the fact that not all solutions solve all problems.
And yes, the government should spend money to help society. I get that. But there are limits. Too many of these and the defense sector would no longer be the bad guy in government spending.
And don't use the relaxing/reading argument. Obviously, you've never had to actually commute on a regular basis on public transit. I used to use a commuter in Portland for a few years. Your quality of reading comprehension sucks and you spend the first hour just trying to fully wake up because you wake up damn early to make your line jumps. It's not like "Oh, the commuter train takes me exactly where I want to go". Nope, now you have to jump onto buses or other lines to get to where you work. Because the stations are never where you need them. And god damn, when it snows and you're waiting outside. Fuck. Oh, and you have to work late that day? Guess what, the commuter only runs at peak hour work days. You don't get to hang out in the city. If you do, call a friend with a car. Oh, and you owe them gas money now too.
