Incorrect. The US is made up of a huge swath of towns and cities that wouldn’t even exist without railways. https://vividmaps.com/railroads-in-america/ You say that every other method of travel is more expensive…but that doesn’t really pass the sniff test, does it? The Big Dig in Boston adjusted for inflation cost more than New York City’s “world’s most expensive stretch of subway.” The California high speed rail pro…

In the poorest countries the most common substitutes for driving are either just not traveling long distances or busses, not trains. Working train networks are very rare in third world countries. So, yeah, they are jumping on cars and highways, just not cars they own personally.

Imo it's matter of political will. They could just redirect money spent on roads& highways to build a good rail infra between major cities for 5 years and ppl would use them. Govs on the other hand prefer to spend money on car infra an subsidize it(pretty minimal costs of owning a car despite of big infra costs, free parking, not accounting for environment damage, etc...

The original Hyperloop paper had a lot of gaps. How does the thing move in low speed until it's fast enough to have aerodynamic lift? Does it use wheels? I don't think the paper talked about it. You do need a good business model and a solid technical foundation. Hyperloop needs a lot of technical work still. Arguably this was also true of SpaceX in the early days, but Elon (and the team he assembled) could execute be…

Why required for mars colony? What is wrong with an air isolated train and just rails? Much cheaper to build

The people of Singapore pay a minimum of 100K for the privilege of owning a bottom tier car and the demand for cars there is overwhelming and insatiable, despite the world class and extremely clean mass transit systems. The reality is that cars are freedom and still superior from a continence and comfort standpoint. Americans are insanely privileged to have cheap, powerful cars.

> The reality is that cars are freedom You are not allowed to run a small business out of your house in US, so i dont think you have any freedom. Private jets are freedom. like actual freedom.

You can do private business out of your house for food at least in California. Or you can just ignore whatever podunk laws they’re supposed to enforce because in the PNW, the cops are too lazy to enforce anti heroin laws let alone anti small business laws

I’ve slowly lost my innocence when it comes to public transportation in the US. At this point I can see that 95% of the country is absolutely locked into low-density single occupancy transportation at least till we invent sky cars. We have trillions in sunk cost that covers nearly every road, every home and every business in America. We will never, ever be Europe.

We can’t possibly have transportation infrastructure like Europe until we have similar zoning laws (which would do away with the separation of homes and businesses into distinct areas) and similar population density. Until we put shops very close to homes, end the huge big-box retailer’s death grip on everyone’s spending habits, and learn to live leaner, European style public transport will never work. We put shoppin…

> similar population density

I agree with rest of the comment, but I feel that connection between walkability and population density is misunderstood. It's not "we need XXX people/sq. mile in US to have walkability", it's "allowing walkability and building corresponding infrastructure leads to increase in local density in places where people want to live".

That sounds like railroads but worse. What's the advantage? Tunneling is incredibly expensive to do, yet you're proposing it in a situation where it'd need enough coverage so as to ban large freight transport over roads.

The one advantage I can think of is no weather to deal with like snow/ice.

Is this a problem for rail? Afaik they just put some special thing in the front of the train to clean up the snow

Much like highways and trains, the tracks are the easy part. The hard part is in routing and termination - think interchanges, onramps, and offramps. Being underground compounds the routing and termination problem dramatically.

I think it also massively complicates the failure modes. Freight trains pretty frequently lose cargo and or derail. That's probably way more annoying to deal with if it's in a really long tunnel.

Only in the USA. Derailments are rare where the tracks are properly maintained, and train lengths aren't excessive.

Its away from weather and extreme temp changes. Its super common in Australia for railways to shut down due to warping of the rails from heat.

I'm not sure, but maybe it's just a problem of their design? There are many countries where rail works fine even during summer

There is a world where we dig tunnels under federal highways, and stick freight trucks down there. They'd run on a monorail, at 120+ mph. Surface vehicles would be dramatically limited in terms of height, width, and length. Maybe people buses could go down there? In my imagination these tunnels are, like, 200' down. Like mole people.

Right, they can even do this for within city delivery. Imagine each home having a tube box, like a mailbox, that is vertically connected to the network of tubes underground. Small electric vehicles running through the tubes and carrying parcel from warehouse hubs to homes and even vice versa. Amazon Instant Delivery!

Afaik Estonia has something similar for their trash system

The Singapore thing is about status, not freedom. For the last 15 years I've lived in various places around the world, and for all of them a private car is the most frustrating, least enabling method of transport available. Finding parking is a nightmare, traffic is a nightmare, having to concentrate on the idiots around me is a nightmare, not being able to drink when I go out is a nightmare, dealing with the mechani…

Add riding a bike (or electric bike) in most of Dutch cities. It can be even fun.

I have a car and a bike in the Netherlands. Most everyone I know has both. Both are nice to have at different times, and I've never experienced any of the nightmares GP is describing.

I was curious so I just checked, and the number of cars is just shy of the number of people of driving age, even in the bicycle paradise of the Netherlands.
