This has a wonderful retro-science-fiction "what if we dug tunnels badly in the 1950s and drove around in them" feel to it. Like Asimov "caves of steel" but .. smaller. Because who has the time to make giant underground caverns for post-destructionist revolutionaries to meet in as autonomous cars whizz by. (what kind of a name is Elijah anyway? at least his wife had a decent name like Jezabel)

I have nothing in principle against tunnels, or even these tunnels except some things which should be simple like underground stations and passing places and making the thing buttery smooth-as seem to have been lost on the expedited need to do it cheap and fast. its CAP theorem for tunnels: you can have good, or you can have cheap and fast. you can't have all three. and if you want good you can't have two of them.

The boring company is a giant con job. TBM are well understood, as is the systematic processes to make tunnels at scale. LV is one of the cheapest places to dig, London used to be because the London clay was load bearing, waterproof and provided input stock for brick building. LV is at least not stone. London has so many tunnels they have to go deeper now. The clay is warming up too. You can't run trains for 100 years without dumping thermal into the system. If you have never seen the cleaner systems in the London Tube, think about what comes out of your ear and your belly button and then scale it up 1000x and add rats.

The main critique I have echoes things others will say better: It's just wrong to make this kind of thing private. Public transport should be built by the public for the public. Now, I know there's a heap of religion built up in that, but if you want to argue for private roads, go to the outskirts of D.C. and talk to any worker who has to transit over what Macquarie Bank calls the giant american cash machine. It's just wrong to do it this way.
