Uber says self-driving car software missed a red light

Last year, a self-driving Uber car sped through a red light in San Francisco, an error the company attributed to the safety driver in the car—but that's not so, according to a report from the New York Times.

At the time of the incident, the self-driving Volvo car was driving itself and failed to recognize the red light, according to a document obtained by the Times.

What happened: Uber said that it was "due to human error," which many took to mean that a safety driver was in control of the car. Now, it appears that the driver's mistake was in not taking control over the car in time to stop at the red light. Uber's statement:

"Our self-driving technology required human intervention. The vehicle operator had time to intervene, but failed to take over before crossing the stop line and manually proceeded through the protected crosswalk."
