LOS ANGELES—Billionaire businessman Elon Musk is promising the public “free rides” in the next few months through the first high-speed passenger tunnel drilled beneath Los Angeles by his aptly named underground transit venture, the Boring Company.
The question is whether the tunnel as advertised by Musk on social media will live up to the sensation he stirred by suggesting commuters will soon get to sample a new subterranean traffic system he has under development in the nation’s second-largest city.
