  If he's looking for mega-good, Musk would do significantly 
  better to drop a full subway network.

Like Hyperloop?

Hyperloop was a completely infeasible design that Musk quite openly had no intention of building. It mainly seemed to exist as a tactic to attack actual planned public transport expansion in the Bay Area, which Musk compared it unfavourably to based on figures that didn't add up.

I bet this tunnel boring idea was inspired by the lack of an economical path for hyperloop to get to downtown LA. The hyperloop concept took a lot of heat for that.

This is to subways like hyperloop is to high-speed rail. A stupid overelaboration of an existing, proven idea.
