Now i'm not going to pretend to even know anything about tunnel boring, but are those the only "errors" that are worth fixing?

I'm assuming if the Boring Company is moving forward, that they have actually done the research and found that those problems are:

* rare enough not to worry about at this point in the game

* have no good possible solutions that anyone can think up right now

* don't have any obvious places where big improvements can be made

* they don't have access to the details of exactly what mistakes were made in those projects because the industry is unable or unwilling to share the information.

* there are solutions to those problems, but they require that other "seemingly solved" problems be optimized or solved differently

Not to mention that they are completely new at this as a company. Getting a few easy wins, validating that your plans and ideas are on the right track, and making sure you really know the problem before diving in headfirst sound like pretty good ideas.
