It certainly looks that way but you can't always trust the Internet.
When Tesla launched Autopilot quite a few people were worried that drivers would exploit the system, say to take a nap. Now the automaker put safeguards into the system to ensure this didn't happen. In our limited time with the Tesla Model S we didn't get to fully experience these safeguards but they do include periodic requests for the driver to touch the steering wheel. If the driver doesn't respond to the initial buzzer alarm that prompts the command then it will continue to sound before eventually stopping if you ignore it too long.
That's all well and good, but does it explain what's happening in this video? It appears the person behind the wheel is asleep, although this video could be a hoax. Yes, traffic is moving slowly but falling asleep behind the wheel is never a good idea. Check it out for yourself and let us know what you think is going down.
