It turns out driving drunk is still illegal, even with a driver-assistance system active. "On Saturday, January 13, police discovered a man in his Tesla vehicle on the San Francisco-Oakland Bay Bridge," reports Ars Technica. "The San Francisco Chronicle reports that 'the man had apparently passed out in the stopped car while stuck in the flow of busy bridge traffic at 5:30pm, according to the California Highway Patrol." From the report: When police woke the man up, he assured officers that everything was fine because the car was "on autopilot." No one was injured in the incident, and the California Highway Patrol made a snarky tweet about it. Needless to say, other Tesla owners -- and people who own competing systems like Cadillac's Super Cruise -- should not follow this guy's example. No cars on the market right now have fully driverless technology available. Autopilot, Supercruise, and other products are driver assistance products -- they're designed to operate with an attentive human driver as a backup. Driving drunk using one of these systems is just as illegal as driving drunk in a conventional car.
