The detection of the cones isn't the problem. The software properly identified that there were cones near the roadway, that's why it stopped. The really hard problem is programming decision-making logic that will properly ignore cones that aren't in the roadway, 100 times out of 100. I used to do QA for the Waymo cars, and boy do they get worked into a tizzy if there's any kind of construction going on. It was the most common situation for remote assistance (read: people sitting in a room sending pathfinding suggestions) to get involved. Judging from some of these comments, the problem is still very difficult.
