Apples and oranges false equivocation of vastly different engineering problems. The problem with vacuum trains is they aren't workable with current materials, are impractical, and are too damn expensive. https://youtu.be/RNFesa01llk

I didn't watch the entire 28 minute video, but I did watch the first part and the creator has a misconception that you share. It's key to understand that the Hyperloop concept uses low pressure (around 100 Pa), not a vacuum.

For all practical purposes, there's no meaningful difference between a full vacuum and a partial vacuum in this context. For example, the energy stored in the vacuum is nearly the same, so in case of explosive decompression, the partial vacuum will do 99% as much damage as a full vacuum.

In other words, the misconception is yours.

Meanwhile China has built 42,000km (26,100 miles) of high speed rail. https://www.travelchinaguide.com/china-trains/high-speed/rai... US is now cursed by their own success. Eisenhower jump started the highway to connect all of US as the largest transport infrastructure project. We have been riding the success of that for a massive economy. We are on the plateauing side of that S curve. cursed because we spent a ton o…

Why do people say 'we don't have the money' for stuff like infrastructure? We never have a problem finding the 'trillions of dollars for wars'. It seems there is only ever a problem coming up with funds these days when it is to invest in things that help our own citizens (outside of just throwing money at them).

Because the debt is now due?

As a bicyclist: no. The problem is the disparity of speed between travelers, same as for a highway. Pedestrians appear suddenly or don't know about your sudden appearance or intended motions, and pain or injury results.

As another bicyclist: yes. That's how we do it here in Tokyo. Almost no one rides on the roads, despite the painted bike lanes that are always ignored by cars and delivery trucks using them as parking spaces.

As a pedestrian in Tokyo, I'm very aware not to make any sudden direction changes in case there's a bicycle behind me.

I've also seen bicyclists trying to make their way through crowds riding a bike where there is barely room for people to walk.

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.

A difference is most Dutch families have one car, whereas the majority of American families have two or more.

Because in America, if you car breaks down, you're fscked.

The so-called Modern Monetary Theory (MMT) credibly posits that because the U.S. borrows in its own currency (dollars), it can simply "print money" as needed — as long as the U.S. economy has sufficient unused productive capacity to absorb the resulting increase in demand. [0]

Yes, and we have generations of people trained to think that walking further than a hundred feet is an extreme workout to be avoided and that transit systems are full of criminals. It seems like that culture is headed for a cliff, however, as the cost of cars continues to increase (the average sale last year was a year’s median pay!), budgets for road infrastructure become tighter, and climate change becomes harder t…

> we have generations of people trained to think that … transit systems are full of criminals Are they not? The BART Police Department's reports for 2022 show the following numbers for Part 1 UCR Crimes: Homicide: 3 Rape: 4 Robbery: 156 Aggravated Assault: 81 Burglary (Structural): 17 Larceny & Auto Burglary: 783 Auto Theft: 136 Arson: 10 Property Crime Subtotal: 946 Total: 1,190

Sure, now do the roads outside of the BART system. There have been thousands of car thefts, carjackings, robberies, etc. Crime isn’t a transit phenomenon.

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.

I’m not arguing with you here but it would be interesting to know what about tunnelling is fundamentally expensive. Things I can think of: it is slow, so you burn through a lot of wages. To compare with road building the only major road I can think of, built in my lifetime, was the M40. It is 90 miles long and took 4 years to build but I don’t know what the cost was. The channel tunnel is much smaller than a freeway…

A road is just 2d tunnel.

A few years ago we had an opportunity to borrow at a negative interest rate. Should have leaned into that opportunity.

Also we’re under-taxing bajillionaires and politically-active but tax-exempt megachurches.

As someone who just moved here: this is by far my least favorite part of moving around in the city; and having to dodge bikes on the sidewalks is the worst part of my commute.

Then stop dodging them: pedestrians like you are the worst. Just walk in a straight line where you're going and stop moving around so erratically; let the cyclists go around you. Anyway, it would be nice if they built some nice, protected bike lanes, but they'd have to remove lanes from the cars to do that.

That doesn't really work on narrower walking paths, with other pedestrians also coming from the other directions; but maybe I'm just unused to it.

I'll... try to be more assertive, I guess we'll see how that works out.

This is true, and I think it’s driving a lot of generational backlash because a lot of younger people are realizing they may never be able to afford to have a commute under an hour, or paid well enough to ignore the mounting costs of that lifestyle, especially as a lot of the infrastructure costs are going up sharply to deal with maintenance.
