Tesla is putting 'self-driving' in the hands of drivers amid criticism the tech is not ready

Waymo conducted 1.45 million miles' worth of autonomous vehicle testing in California last year, the company reported to the state Department of Motor Vehicles. Tesla vehicles drove a total of 12.2 autonomous miles, to record what it called a "demo run" around its Palo Alto headquarters. Tesla has argued that it "has a fleet of hundreds of thousands of customer-owned vehicles that test autonomous technology in'shadow-mode' during their normal operation," constantly improving through billions of miles of real-world driving. Shadow Mode allows it to test some of those automated features without actually activating them in the real world.
