A company owned by Elon Musk may bring a transit project to San Antonio. The Alamo Regional Mobility Authority is accepting proposals for a project to link downtown and the San Antonio International Airport. The Boring Company has been working to bring hyperloop travel to several markets. The company has already built such a project in Las Vegas that opened earlier this year. An actual hyperloop offers fully autonomous high-speed travel, and may be years away. Musk's current offering reportedly involves Teslas in tunnels.
