In 2016, Elon Musk founded The Boring Company, an infrastructure and tunnel construction enterprise, which by 2017 filed permitting application with Los Angeles government regulators to build a tunnel from Hawthorne to Westwood.
Aside from application as a high-speed shortcut, Musk said that the goal of the company is to make establishing a tunnel network financially feasible by enhancing tunnelling speed. He also said earlier that "getting good at digging tunnels could be really helpful for Mars."
