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

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. First, the Waymo vehicle paused at a stop sign rather than turning onto a street lined with cones. Human motorists had to cross a double yellow line to go around the Waymo vehicle. Then, as the human driver approached, the Waymo car drove away again, but only a short distance.
