A disturbing video appears to show a driver fast asleep in his Tesla Model 3 as the car sails down the 405 Freeway in Los Angeles during rush hour traffic.
A viewer noticed him at the 405 and 5 Freeway interchange.
He said he called 911 when he saw the sleepy driver.
He said the driver was still passed out when he took the 110 Freeway exit.
People are questioning: As more people drive using autopilot, how do you keep them from dozing and driving?
