The road this happened on frequently has three lanes on a carriageway. I can easily imagine a situation where the cars in question are in the left-most and right-most lanes, and both want to move into the middle lane. Both "see" that the lane is empty and both make their move at the same time. I wonder if these self-driving cars can "see" a turn signal two lanes away. Of course, we don't know if the Google car was in self-driving mode or was being operated by a person. The article only tells one side of the story.
