Elon Musk is serious about tunneling

So much so that there’s official merchandise for “The Boring Company.” Elon Musk tweeted this yesterday:

In January, Musk’s team began to dug a test trench 30 feet wide, 50 feet long and 15 feet deep at the SpaceX Los Angeles headquarters in the suburb of Hawthorne. The idea is to build a network of tunnels underneath the city that would allow people to travel underground. All this in response to Musk’s frustration with LA traffic:

Los Angeles city officials have not as of yet granted Musk permission to dig on public ground. But if he’s going to solve the traffic problem in LA, I say give let him go to town.
