Is the madman really doing it? Well, he keeps tweeting about it, and in a seemingly serious manner, too, although it sounds like more of a personalized, pet project now that would only help him get between LAX and his SpaceX office. The overall idea was for these tunnels to reduce traffic, but I think the real solution for something like that would require figuring out how to get people off roads. Elon Musk said he’s making “progress” on his tunnel ambitions on Twitter on Wednesday, a project he first mentioned after being stuck in traffic in LA in December. The SpaceX and Tesla CEO shared more details about the project when pressed by fans, specifying that he could actually plan to start digging essentially from near his office at SpaceX. Musk’s tunnel plans, then, seem possibly aimed at reducing his travel time between SpaceX and LAX, at least initially. LAX is an airport he likely frequents with dizzying regularity, given his commitments at SpaceX, Tesla and SolarCity. In Ashlee Vance’s 2015 biography, he said Musk essentially splits time between SpaceX and Tesla HQs, which means a regular mid-week and end-of week trip to and from Silicon Valley from LA.
