The billionaire businessman Elon Musk told a cheering crowd that his dream of burrowing a high-speed network of "personalised mass transit" tunnels under Los Angeles could be achieved without disturbance or noise.
Musk said that the full-fledged project would involve a tunnel along the Los Angeles' scandalously busy 405 Freeway where the traffic differed between the seventh and the eighth circles of hell.
His celebrity status preceded him with some visitors pushing their way into the crowded hall...
Whether staunch critics were swayed remained to be seen.
Although the tunnels are only just in the testing phases, with LA city officials giving the OK for 2.7 miles of track, Musk plans to build an entire network underneath the city, accessible through hundreds of mini stations, approximately the size of a parking spot.
The Boring expansion comes as Musk wrestles with production problems for the rollout of the Model 3 sedan at Tesla, his electric auto and energy-storage business. Just last month, SEC documents were filed detailing that Musk's Boring Company had raised just shy of $113 million.
Meghan Markle's Half-Sister Reportedly Hospitalized After 'Confrontation' With Paparazzi, 'TMZ' Reports
Meghan Markle's wedding week has hit another snag - her half-sister has been hospitalised with a broken ankle and fractured knee. Samantha went on Good Morning Britain on May 15 and host Piers Morgan tore her a new one when she called the media "vultures".
But Musk denied trying to take any shortcuts, saying even with the waiver, Boring faces "600 pages of permits that would be required for this tunnel". The project would involve hundreds of entrances where travelers in pods could descend to the network of tunnels that will shuttle them at high speeds across the city.
The test tunnel will stretch almost three miles along Sepulveda on LA's Westside, one of the most traffic-congested parts of the city.
The West L.A. tunnel is the latest project Boring has undertaken after quietly digging a slightly shorter tunnel underneath tiny neighboring municipality of Hawthorne, where SpaceX and Boring are both headquartered.
Musk also imagined that the city's roads could become parks or gardens, and said the tunnels could be "almost like an autonomous, underground multi-level auto system".
"Compared to a flying auto, you don't have to worry about bad weather, you can't see it, hear it, feel it".
Musk, the Silicon Valley high-tech tycoon best known for his Tesla Inc electric auto manufacturer, planned to make a rare personal appearance at a public event in Los Angeles on Thursday night to answer questions from residents about his tunneling plans.
