It certainly matters: "average driver" does not exist, and 95% of the drivers beat the average. So a claim how autonomous driving system beats the average would only tell us that it beats 5% of the human drivers. Now, the way stats are massaged here is not even about "drivers", but miles driven, and this language is even worse. We'd need to make sure we are looking at human-driven miles in the same area, same roads, with similar cars.
