So, as someone that lived in New York for 6 years and California for 6 years, stories like this are incredibly depressing. The US is the world's largest economy and should be the shining example of amazing infrastructure, high-tech, green cities, and forward thinking policies. California is an especially egregious example in terms of infrastructure investment: If California was a country it would be the world's fifth…

"The US is the world's largest economy…"

If your Federal Reserve stopping adding nonsense imputed and hedonic values to the tune of about ~$7 trillion to your economy's GDP, you would find yourself in second place.

Which might make help explain away your confusion :)

Isn't Tesla working on Ultra-Fast 'Hyperloop' Trains?

Isn't it Elon, not Tesla?

You're absolutely right.

Has anyone else here ridden the maglev in Shanghai out of the airport? My 2c is that it was awesomely fast and convenient. BUT, I was a little unnerved by how much the train jostled at some points. It was like the supports for the track had sunk in some places leading to the tracks no longer being aligned. Not really informed by anything concrete, but I think there’s a disaster waiting to happen there. China has nowh…

I rode it ten years ago and it felt safe, I would be interested to know how safety would be for a 1000 mile trip where every inch of track couldn’t be controlled. An animal on the track, sabotage, ice, snow — there are a lot of factors that become very hard to control at those speeds and distances.

I haven't looked at the particulars for this project, but typically the practical limit of high speed rail is 300-500 miles. Beyond that, it's cheaper and greener to fly.

If you aren't concerned with cheap or green, and want to focus on fast... Then high speed rail might be a better option until the TSA is involved.

What is the cost of riding one of these?

The current HSR from Wuhan to HK is USD $96/$154/$298 for 2nd/1st/business class seats respectively. It’s all price regulated, so that’s the cost for every train on that route, every day.

That applies only to insinuation, i.e. vague hints and suggestions made without giving evidence. I'm not insinuating but outright accusing OP to be a Chinese shill on the basis of his posting history. The evidence is there in his post history for all to see.

No, that difference does not exist.

Look it up in the dictionary

https://www.youtube.com/watch?v=0JDoll8OEFE Please, I urge you to watch this. It explains thoroughly why the situation for railroads is very different between China and America. tl;dw: America is more spread out, has better airline control, and less of a political incentive to expand public transport, than China.

Isn't the density a bad excuse since you can add the infrastructure only in regions with large density like California?

Yeah - this is why I find that argument very specious. Florida has a higher population density than France but there's no TGV equivalent running from Jacksonville to Miami

I'm not talking about the dictionary definition, I talk about what the HN rule means and how moderators enforce it. If you need to dictionary-lawyer your rule violations it seldom does you good.

Well, how do you know what the rules mean? You have no direct access to dang's head. All one can rely on is the explicit words written, and the meanings of those words as defined by the dictionary.

Since when is air ever greener than rail? Everything I've seen puts air at a hugely higher carbon impact.
