Here’s a gentleman taking a nap while his Tesla drives for him.
From Electrek:
Tesla’s Autopilot requires the driver to always monitor the vehicle and be ready to take control. If the system lacks data to continue to actively steer the vehicle safely, it will show an alert on the dashboard.
If the driver ignores the alert for too long, it will emit a sound and decelerate while activating the hazard lights and moving the vehicle to the side of the road. The vehicle basically assumes that the driver is unconscious if he can’t take control after visual and audible alerts.
In this case, it seems like the Autopilot is still very much in control and therefore is not bothering the sleeping driver – now a simple passenger.
