I am in a Tesla Model X, behind a storefront Elon Musk plans to use to sell bricks. The bricks will come from dirt excavated from tunnels like the one I am about to enter. This is O’Leary Station. The Model X, which is playing Faith No More’s “Epic,” pulls up to a place about the size of two standard parking spots and stops. People dressed entirely in black — black broken only by the white logo of The Boring Company — surround the car. And they get taller as the car starts to sink.
