In 2017, Musk founded the Boring Company to construct tunnels, and revealed plans for specialized, underground, high-occupancy vehicles that could travel up to 150 miles per hour (240 km/h) and thus circumvent above-ground traffic in major cities.[156][157] Early in 2017, the company began discussions with regulatory bodies and initiated construction of a 30-foot (9.1 m) wide, 50-foot (15 m) long, and 15-foot (4.6 m) deep "test trench" on the premises of SpaceX's offices, as that required no permits.[158] The Los Angeles tunnel, less than two miles (3.2 km) in length, debuted to journalists in 2018. It used Tesla Model Xs and was reported to be a rough ride while traveling at suboptimal speeds.[159] Two tunnel projects announced in 2018, in Chicago and West Los Angeles, have been canceled.[160][161] However, a tunnel beneath the Las Vegas Convention Center was completed in early 2021.[162] Local officials have approved further expansions of the tunnel system.[163]
