La La Land is known for horrendously bad traffic, but the billionaire businessman's Boring Company has come up with a way for commuters to travel at a speedy 150mph on the Tesla Model S vehicle.
Unveiling the test tunnel, he said: "At that speed, it will feel like teleporting within a city.
"It's much more like an underground highway than it is a subway.
"It's not like you're going through a whole series of stops.
"Nope, the main arteries will be going super fast, and it's only when you want to get off the loop system that you slow down."
Musk explained that passengers board at the
O'Leary Station and are taken underground by a lift, and revealed it will may be possible for offices to have their own fitted in the future.
He explained: "The purpose is to demonstrate that a lift can be built in very small footprints and within existing buildings, whether they are houses, office buildings, or retail parking lots.
"Looking forward, one could have a lift in the basement of every office building, allowing extremely convenient commutes."
After his first ride at the test tunnel, he said: "For me it was a 'eureka' moment. I was like, 'this thing is going to damn well work'."
The test tunnel, which is essentially a two-mile long underground track cost $10million (£7.9million) to build, but the Tesla CEO believes it will be possible to reduce the price in the future.
