SpaceX and Tesla CEO Elon Musk late last year announced his intent to build a network of underground tunnels to help drivers avoid congestion, and now we finally have an idea of how the system will work, if the plan actually comes to fruition.

The Boring Company, Musk's latest project, on Friday posted a video offering a first look at the underground transportation system it's hoping to develop. As you can see below, drivers would pull their car onto a metal platform on the side of the road, and the vehicle would then be lowered into the underground tunnel system.

Based on the video, it looks like drivers would then be able to sit back and take a break. Their car would remain on the metal platform (reportedly called a "skate") and be transported through the tunnel at around 124mph.

Musk first announced his boring ambitions on Twitter in December.

"Traffic is driving me nuts. Am going to build a tunnel boring machine and just start digging..." he wrote, following that up with another tweet saying, "I am actually going to do this."

Turns out, he was serious. In January, Musk said he's making "progress on the tunnel front," and planned to start digging "in a month or so."

During a TED Talk on Friday, Musk said the skate would transport cars through the tunnel at up to 130mph, according to Business Insider. At that rate, you'd be able to get from Westwood to Los Angeles in five minutes, he reportedly said.

There's at least one major problem holding back this plan at the moment: tunnel boring is a ridiculously slow process. Musk and The Boring Company are aiming to build a better boring machine — one that can dig a tunnel and reinforce its walls at the same time — to speed up the process.

"We have a pet snail called Gary. ... So Gary is capable of currently going 14 times faster than a tunnel boring machine," Musk said, according to Business Insider. "We want to beat Gary."
