Elon Musk, the billionaire CEO of Tesla Motors and SpaceX, insists he’s really going to build a tunnel-boring machine to do something about road traffic. But should he?

Three years ago, he came up with the Hyperloop concept for near-supersonic land travel out of frustration with California’s costly plan for a rapid-transit system that’s not that rapid.
Now it’s tunnels.
