That's the entire point of The Boring Company. It's way more expensive than anyone expects. That's the problem they are trying to solve. The entire goal is "serious advances in rock boring techniques". That may be a lofty goal, but at least the message I got is that it is the one they want to reach.

>> "(personal opinion: there are none coming)" Former tunnel boring engineer here. There is a ton of room for innovation around tunnel boring machines built by the major manufacturers (primarily Herrenknecht and Robbins), around reliability, durability, ease of serviceability etc. I cannot emphasize enough how modern TBM's require an unbelievable amount of engineering attention, repair labor, spare parts infrastructu…

That's a lot of good insight into tunnel boring. Thanks for that.

I know Cincinnati's subway failed because of some bad tunnelling that caused foundations to sink .. well that and the great depression. If they had started earlier or designed it better, Cincinnati could have a Chicago like transit system today. Unfortunately it took them years to get a tram and there are people still trying to shut that down instead of expand it! Unbelievable.

I know in Seattle, many of the tunnels (like to Northgate/UDistrict) have actually been fully bored. The new stations are still not due to open for a few years, mostly because the majority of time isn't spend on the tunnels, but installing track, electrics and building the underground rail stations.

This was exactly my thought as I watched the video.

What we really need to do is to figure out ways that reduce the need for all this transportation. When you look at it from a distance almost none of it makes sense. The only travel that really needs doing is people working with physical stuff, moving the goods themselves around and leisure travel (and that one is definitely not a must but it is hard to make a stand-in experience that is comparable to the real one). M…

Robots doing physical work, people discussing strategies in conf room with collaborative tools. Problem solved ?

Dense cities and narrow streets would solve the same problems with fewer technical demands. Look up New World Economics and "Really Narrow Streets"; the author provides a blueprint of sorts for traditional cities with minimal commute/transport expenses.

Here's a question for those way smarter than me. Why is there a need for a platform?

Some pros: - If its a shitty, poor regulated car.. this will lead to more safety - Avoid adding extra gear (software/hardware) to the car

Cons: - Size restriction - Clean up and Maintenance - How do you ensure the car is in the platform securely?

The video shows some sort of shuttle using the track. Those could be small busses or even public transport. http://imgur.com/a/Wv8YD In effect, this is a subway system. It's an underground rail system. The major difference is that you have a mixture of public and private passenger vehicles and smaller vehicles.

It's still incredibly wasteful compared to a real subway. The amount of people a real mass transit system can move is orders of magnitude above tons if individual little cars: http://penguindreams.org/blog/self-driving-cars-will-not-sol... ..not to mention all the energy required to move each of those vehicles compared to a train that can move hundreds of more people in a similar space. Americans need to get over all…

One weakness of all public transportation is the lack of personal space. Maybe if someone would have solved that either by more space or some deep psychological insights, it would become more popular among Americans?

But can you get a moving block signalling system such that they can follow each other with minimal separation? Until you can do that, a real train will always win at people/hour due to the fact that you can have more people per consist as ultimately the signalling challenges are comparable and you can therefore have comparable separation.

With all my sympathy for metro - in many American cities it will never be good enough due to extensive suburbs. In places where land is cheap, and there are single family houses, cars will be the most efficient way to commute for years to come. We'll switch to self-driving electric cars, but still.

But ultimately you aren't going to have tunnels dug by the Boring Company out into the extensive suburbs either. The question ultimately becomes whether it makes sense to give up large amounts of space (even if underground) in the centre for parking (for everyone commuting from the suburbs), or give up space further out where land is cheaper and less dense for large car parks at stations. (Obviously there's a cost in changing mode of transport, but that somewhat applies to the pods too.)

I have to give Elon Musk credit - the average person would be hard-pressed to come up with even a single laughably impractical mode of transportation, but he's got two.

Actually he has 3... Rocketry is a pretty impractical mode of transportation as well.

It's the only practical way to get to space and stay there...

The thing to do is to check for what is potentially inconsistent with your hypothesis. For example, what about the neural link company?

64 LA subway cars cost $176 million [1]. That seems really high to me, at about $3 million per subway car.

Also people per hour is not really the metric the average person cares about. It's travel time to destination.

Since this is a thread about Elon Musk, transportation infrastructure, public transportation, and urban design, and because HN has a sort of affinity for the Robert Moses story (The Power Broker was one of 'aaronsw's favorite books), this seems like a particularly on-point Twitter thread to read after the video: https://twitter.com/EmilyGorcenski/status/858022699112824832 You might not agree with all/any of it but I…

It's not thought provoking, it's a series of thought terminating cliches. I'm as liberal as they come, I'm very sensitive to disguised racism, but the tweets' entire basis of comparison between Musk and Moses is "both are/were ambitious men and now musk is talking about infrastructure". It's free-association garbage. The Moses story is fascinating because he accomplished great things that built NYC but was also a hor…

Moses wasn't a horrible person. He was an ambitious, unscrupulous, and effective person with a singular view --- one not totally out of step with the elite of his time --- that happened to be (in the opinion of many, including me) very harmful to the long-term health of New York.

I think it's your rebuttal that's facile here, not the comparison in the Twitter thread, but, like you, I might be wrong.
