The Albany Gazette - Driverless car stopped in San Francisco puzzles cops

The vehicle, it turned out, was a self-driving car, and the police officer's encounter was captured on film by a passerby, who posted the footage on social media.

The clip, showing bemused officers circling the vehicle and peering through its window for several minutes, has been shared so widely that Cruise, the company that owns the vehicle, reacted on Twitter to explain what had happened.

It said the self-driving car "yielded to the police vehicle, then pulled over to the nearest safe location for the traffic stop, as intended. An officer contacted Cruise personnel and no citation was issued."

In the footage, as the police are inspecting the parked vehicle, someone can be heard exclaiming, "There's no one in it, it's crazy!"

A police spokesperson said that after the police had stopped the car, a maintenance team had taken control of it.

Cruise explained that the headlights were turned off due to human error.

Founded in 2013, Cruise has developed software that allows cars to drive themselves completely autonomously.

The US manufacturer General Motors owns the majority of shares in the company, valued at more than $30 billion thanks to investments by giants such as Microsoft, Honda and Walmart.

Since February, Cruise has passed a key threshold in offering individuals the chance to book free trips in the streets of San Francisco in its driverless cars.

Residents of the Californian city also regularly come across robo-taxis from Waymo, Google's self-driving subsidiary.

These camera-clad vehicles take passengers wherever they want, with a driver who is present but does not touch the steering wheel or the pedals.
