Elon Musk’s plan to dig tunnels under cities for cars to circumvent traffic is coming to fruition — starting in the SpaceX parking lot in Los Angeles.

The serial entrepreneur is breaking ground with his new startup The Boring Company, which Musk says should have its first car elevator operating next week.

The idea with the Boring Company — which Musk first introduced in a series of tweets last December while lamenting about how much he hated sitting in traffic — is to lower cars underground with an elevator. The cars will then travel on a platform, like a skate, to zip through a tunnel at speeds up to 130 miles per hour.

Musk shared on Twitter a short video of the car elevator being built that goes underground Friday; he says it should be operational next week:

The tunnel digging machine is named Godot, inspired by Samuel Beckett’s famous 1953 play about procrastination, “Waiting for Godot.”

It’s not clear whether the Boring Company has been successful in getting permission from the city of LA, but Musk says he has had talks with the mayor, pointing out that it will be harder to get regulatory approval for his tunnels than figure out the technology.
