Yes, it will cost a ton of money. Hundreds of billions, doubtless.

A replacement infrastructure would probably cost a lot more than that if you are talking about putting not only the local infrastructure (subways and such) but connecting the cities together as well. You’d have to build the system over decades..and where is the demand for it? Where are the teaming millions yearning for HSR? They don’t exist…so, you’d be creating a huge new costly system on the chance that you guessed right and people would (eventually) use it. Until they did you’d have a huge an costly white elephant that also costs a lot to maintain and subsidize.

But Americans collectively need to own up to the fact that the days of driving when and where we pleased in gasoline-powered cars is coming to an end.
[/QUOTE]
Do they? Why? Even if you have a magic crystal ball and can look into the future it’s going to be rather had convincing American’s that their entire way of life wrt personal transport is going away. That no alternatives exist that will enable them to continue to use personal transport as they have used it for decades. I am unconvinced for that matter that your prediction of the future here is accurate.
[QUOTE=HeyHomie]
We’re going to have to get used to the idea that cars are going to have to a) be used for daily commutes, noodling around town on day-to-day errands, etc.; and b) used as a supplement to a rail system that will be our primary means of going city-to-city.
[/QUOTE]
A) That’s pretty much what people use and will continue to use them for in the future. Unless you meant that cars won’t be used for these things in your predicted future I’m confused.
B) I disagree. Even if you could somehow get enough political support to pay the outrageous costs of putting in a HSR infrastructure to connect some cities together, I doubt this will ever make up the majority of intra-city commuting. It will simply be one more piece of the transport system which includes the road infrastructure and air infrastructure.
Here is the thing…we ALREADY have the first two of those things. I could see (if I squint hard) a limited HSR system being built between a few key hub cities (say New York, Boston, DC/Baltimore, Chicago, Raleigh, Atlanta, Kansas City, Phoenix, LA, San Francisco, Portland, Seattle) a little bit at a time over a couple of decades. But realistically you will probably never even get the political support/will for even this kind of limited system (which would cost hundreds of billions or even trillions to build since you’d have to pretty much build the rail infrastructure from scratch as the current system wouldn’t support high speeds…at least I don’t think it would by and large)…let alone a comprehensive system you’d need to take even a large percentage of cars off the road. And frankly, having built the thing, I doubt most or even many people would use it unless you heavily subsidized the price structure.

That’s how they do it in Europe.
[/QUOTE]
To paraphrase a quote for the book Voyager: “Look around man…dis look like Africa to you??” Sure, they use this system in Europe extensively (they still have a lot of cars though)…but Europe ain’t the US. Europeans didn’t grow their infrastructure around the car for the last century. Their population density and city orientation is different than ours. They aren’t spread out as much as we are. And frankly they STILL have things like the Autobahn that are extensively used even with all that rail infrastructure. The places I’ve been to in Europe seem to be very similar to the US as far as traffic goes…and mass transit is kind of bred in the bone there.
[QUOTE=HeyHomie]
That’s how they do it in Japan.
[/QUOTE]
“Look around man…dis look like Africa to you??”
Have you BEEN to Japan? It’s a small island that more readily lends itself to mass transit like you are talking about. In addition, again, the Japanese didn’t spend the last century building and refining a road infrastructure like we did…they used rail much more extensively all along. Also, having been to Tokyo I can tell you…a hell of a lot of cars are still on the road in Japan and a lot of people drive rather than take the trains (though they DO use their train system extensively).
[QUOTE=HeyHomie]
China is gearing up to do it that way.
[/QUOTE]
Again…no long term history of road infrastructure of personal transport, more oriented toward rail transport both culturally and historically. That said, I recall reading that China is putting more cars on the road each year than even the US these days…so it doesn’t actually look like anyone in your examples is going toward mass transit and phasing out personal…instead it looks to me as if they are either going in the opposite direction or simply balancing more between the two options.
[QUOTE=HeyHomie]
There’s no reason the US can’t do it.
[/QUOTE]
Can’t…or won’t? Off the top of my head I can think of myriad reasons why we haven’t done it and probably won’t either. Costs, both initial (as well as logistics trying to get rights of way and things like that) and periodic for maintenance. Lack of demonstrated market or need for such an extensive system. System would be more inconvenient to American’s than the current two transport systems available.
I have no problem if people have a need for HSR (personally I would love to travel on it at least once) and are willing to pay for it. But to try and create such a system by fiat when there is no demonstrated market for it simply on the off chance that personal transport is somehow doomed in the country? No, I don’t buy that.

We WILL run out of oil.
[/QUOTE]
No…we won’t. Oil will simply become to expensive to burn for personal transport…and possibly to politically or socially unacceptable because of it’s CO2 emissions. But we will never run out of oil. Long before oil becomes to expensive alternatives will emerge.
[QUOTE=HeyHomie]
It may take another 50 years, maybe another 100 years, but either way we’re going to run out.
[/QUOTE]
Well, as I said, we are never going to run out. But IMHO viable alternatives will emerge long before your 50 year prediction (we’ll still have plenty of oil at that point btw…but I think it will become politically and socially unacceptable long before that)…you seriously don’t think that there will be alternatives to the CO2 spewing ICE by that time??
[QUOTE=HeyHomie]
It’s better, IMHO, to be ahead of the curve and have a backup system in place before we absolutely need it.
[/QUOTE]
Well, YMMV…myself I think it’s better if we don’t pour such huge sums into something there is no need for and may never be a need for. Those hundreds of billions of dollars may be better spent elsewhere…or better yet, given back to the folks it was taken from.
