Elon Musk tweeted on Thursday that his tunnel boring machine has completed the first segment of tunnel in Los Angeles.
On Friday, he followed up with images and video of a tunnel — supposedly the same tunnel segment — located at the SpaceX headquarters in Hawthorne, California.
Musk first tweeted an image of the SpaceX headquarters. He then tweeted a video of the tunnel entrance with the caption "across the road and below the ground."
