Elon Musk's Boring Company just released a video that gives an idea of what a massive underground freeway system would look like.
Have a look:
Musk discussed his plan during a talk at a TED conference in Vancouver, Canada, on Friday.
Some people have posted pictures of equipment bearing the Boring Company logo that arrived this week at SpaceX headquarters, in Hawthorne California.
Musk, who currently heads both Tesla and SpaceX, first publicly mentioned his digging project back in December.
