The entire report is devoted to this one incident, likely because of its significance: Google had long held up its lack of caused collisions as a rallying point, but realistically, it was only a matter of time before something went wrong. As the company mentions in the report, a large part of the car‘s job is managing relationships with the human drivers around it — and in this case, the management of that relationship failed. It notes that has „made refinements“ to the software after reviewing the crash and says that it hopes „to handle situations like this more gracefully in the future,“ but realistically, there will always be some degree of uncertainty — at least as long as human drivers are on the road.
