Traffic cones confused a Waymo self-driving car in Arizona. Then things got worse.

A confused Waymo self-driving car was captured on video as it became stranded on an Arizona road earlier this month while carrying a passenger and then unexpectedly driving away as a worker from the company’s roadside assistance arrived to help.

But the Waymo vehicle soon became stuck farther down the road, which was lined with construction cones. The Waymo worker caught up to the vehicle, took over, and drove the paying passenger to his final destination. Waymo operates a limited ridehail service in Chandler, Arizona.
