I disagree, tunnels for transport of both people and goods, especially in high-density urban areas is the best way to go. Walking and biking is great for their distance, but cars and trucks are still needed for larger and heavier items. Using shared transportation (like a train) is terrible for "The last mile". Doing everything at night just seems like a band-aid and sucks for all those workers.

The idea of trying to solve the hard infrastructure problem of digging first also seems like a great idea. Build the aqueduct before you build the millions of houses and farms, and even let anyone do that part.

It's still premature to say that they haven't revolutionized the field, people around the world are still digging tunnels so there's still a market. It wouldn't be the first time an already highly mature field got revolutionized, I still don't get why you're so anti-tunnel.

Here is the thing, you demand incredibly high amounts of capital cost for not actually achieving much. And that capital could be use for far, far, far, far more useful things the city actually needs. Like high capacity transports, like metros, trams or bike lanes.

The amount of goods that need to be transported to stores and such things isn't that big. And using literally free unused roads at night or early in the morning is just a great deal.

For individual transport last mile is regularly being done by cargo bike or small electric truck just fine.

But you are right, tunnels do make sense for some things. Like transporting garbage underground. Or transporting heat underground for district heating, or district cooling. Both would be better investments then trying to move logistics under-ground.

There is a reason, no serious attempt anywhere in the world is trying to move logistics under-ground. There are just so, so many better ways to invest in the city. Its literally not even in the Top 100 most needed things.

Specially in the US where the road network is so hilariously overbuilt that it could serve 10x the amount of people on the same area if public transport was just taken minimally serious. And in the US, underground cargo transport isn't even in the Top 1000 things a city should consider spending money on.

Metros are in tunnels.

There’s only so much gridlock you can avoid without going above or below grade. I was shocked when I moved to Seattle and they had no subway system. It was made even worse by being crammed up against a tall hill with a ridiculously deep lake behind it. They are finally changing it now but I’d spent time in Tokyo before, and time in London and Paris shortly after and it was a real head scratcher. One bus tunnel helped, as was evidenced when they shut it down for a couple years, but cmon.

Seattle also is a great example of "why tunnels for cars are not tantamount to a public transport network".

As well as all the impediments to the glorious vision of the parent commenter's "tunnels everywhere" as a panacea.

Yes, WHEN you build tunnel you need to make it the highest possible capacity. And not some low capacity tax system.

Because The Boring Company hasn't built any tunnels worth noting, perhaps, and stalled most of its projects.

This isn't a case against tunnels, this is a case against The Boring Company.

The tunnels aren't a great idea apriori. Good luck pitching the tunnels idea in Venice.

The tunnels may be a good or a bad idea depending on many variables, and the tunnels that the Boring Company has actually built are worthless.

As for the tunneling equipment: selling those machines isn't their core business, and there's no evidence these machines have, or may in the feasible future, do anything revolutionary in the tunnel industry (i.e., built radically better, radically cheaper, or radically faster).

The idea of having such machines is good. They don't have such machines.

> It's still premature to say that they haven't revolutionized the field

It's never premature to say that. Read what you wrote.

You can say a field has been revolutionized once a revolution takes place.

It's hasn't.

The impact of the Boring company on the way tunnels are dug is, very sharply, zero.

Is it possible that they will? Sure. It's also possible that Britney Spears will. She still has the time, it's premature to say she wouldn't do it, right?
