In a tunnel underneath the streets of Hawthorne, CA, Elon Musk's other, other company is focused on the future of urban mobility. Last evening, the Boring Company invited a select group of people to come and try their first test tunnel. 1.14 miles in length, it was once promised to accommodate cars riding on sleds, but is now built for autonomous electric vehicles outfitted with deployable tracking wheels. The video above shows one of these early test runs, from lowering down the elevator shaft at the start to its return to the surface via a separate elevator at the end. In addition to private vehicles, the company will also operate a number of its own vehicles as public transit, however, no opening date has been set.
