The video above shows a Model S owner with the latest version of its semi-autonomous Autopilot hardware (version 2.5) driving down an Indiana highway. A single lane splits into two, and instead of following either lane correctly, the Autopilot system treated a right-side line as a left-side one, pointing the vehicle squarely at the barrier. The owner was able to stop the vehicle in time, as he was paying attention despite Autopilot pleading for the human to take control.

It should be noted that Autopilot has never been a true substitute for human attention. Driver vigilance is required at all times, and the vehicle will emit multiple warnings when it's time to hand driving back to a human. Tesla reported last week that Autopilot was engaged during the California incident and that the driver did not appear to attempt to retake control. The National Transportation Safety Board is still investigating.
