The Boring Company has raised more than $795 million from venture capitalists on Musk’s big idea: underground, multi-station roadways where autonomous vehicles could shoot off individuals to their destination at speeds of 150 miles per hour. But on the ground, after 7 years, Boring is operating a mere 2.4mi of tunnel. Meanwhile Boring projects from California to Illinois, Texas, Florida, and Maryland have all fizzled or been disbanded.
