On Thanksgiving, the San Francisco Bay Bridge functioned well.

 A Tesla Model S changed lanes and stopped in the fast lane, changing that swiftly.

 Its abruptness caused an eight-car pileup. Nine people—including children—were injured. Tesla self-driving?

The California Public Records Act allowed The Intercept to get photographs of the event. 

 Tesla Autopilot may have triggered the moves. Owner said yes.

The motorist informed authorities that the left turn signal triggered the brakes as it entered the left lane.

Then it stopped “directly in the route of travel.” Bridge videos corroborate the driver's experience.

Coincidentally, Tesla CEO Elon Musk earlier that day stated the "Full Self-Driving" update is ready now.
