Hmm maybe this is what the boring company is trying to do. If they can use their tech to tunnel the same distance at 90% less would truly redefine transport.
There was initial skepticism regarding Musk's predicted [reduced] costs --perhaps he was taking into account the removal of all these excess construction costs much of the public isn't privy to.
Boring itself is highly optimized - the oil industry likes their holes long, stable and cheap. So the tech is there. It is the other stuff that bogs down a project.
