Elon Musk continues to share progress on his plan to build a network of tunnels that carry cars on electric sleds.
Musk posted to Instagram a video of a Tesla Model S being lowered underground on an elevator.
He previously shared a video on Twitter of the elevator’s skeleton being constructed.

According to a concept video, the elevator would lower vehicles into the the tunnel where they would ride a high-speed platform at up to 124 mph.
