Two years after he first announced his plan to avoid traffic and make public transportation more efficient, Musk and his Boring Company are set to open their first test tunnel tonight and reveal the autonomous vehicles that will travel through it at speeds up to 155 miles per hour.
Elon Musk is finally ready to unveil his Boring Company tunnel.
Guests-including officials from other cities that might one day hire Boring Co.to build longer versions of the tunnel, as well as Tesla owners and various other party-goers-quaffed cocktails named after tunnel-boring machines, noshed on hot dogs and stood in line to take rides. Since the announcement, Musk has revealed a handful of photos and videos of the tunnel's progress.
The new tunnel was excavated along a path that runs not through Los Angeles but beneath the tiny adjacent municipality of Hawthorne, where Musk's Boring Company and his SpaceX rocket firm are both headquartered.
Of future systems, he said: "It'll be smooth as glass".
Claiming he is working for the greater good, Mr Musk said: "Traffic is a blight on everyone's life in all cities".
He said every auto could run at top speed when inside the arteries, slowing down to enter and exit.
Musk arrived at Tuesday night's event in a Tesla vehicle so equipped, emerging from the auto at one end of the tunnel - bathed in green and blue interior lights - as he was cheered by a small, enthusiastic crowd gathered for the presentation.
Describing how he felt when he was taken through the demonstration tunnel, Mr Musk said: "I thought it was epic".
Under his visionary plans, vehicles will descend into the tunnel via elevators before being outfitted with retractable side wheels on the tracks.
Mr Musk said the system would operate more like an underground motorway than a subway.
The entrepreneur explained for the first time in detail how the system, which he simply calls "loop", could work on a larger scale beneath cities across the globe.
These wheels would cost about $200-300 (£157-236) per auto.
Musk dismissed concerns such as the noise and disruption of building the tunnels, saying that when workers bored through the end of the test tunnel the people in the home 20 feet (6 meters) away "didn't even stop watching TV".
So began The Boring Company, tongue in cheek intentional.
Chicago chose Boring for its project for a high-speed, capsule-shaped train connecting the city centre to the airport. Musk thinks Boring can lower the cost of tunneling projects while also significantly increasing their speed through some relatively simple changes to the way typical tunneling machines work.
For the privately funded test tunnel, Musk acquired a tunnel-boring machine that had been used in a San Francisco Bay Area project and put it down a shaft in a parking lot at the SpaceX headquarters.
Musk's vision for the underground tunnels is not the same as another of his transportation concepts known as hyperloop.
