That's their average for the year. They were way worse at the beginning, and way better by the end. They continue to improve, though I can't give you data on that until late December when this year's disengagement reports are filed. Like once you get to the point where you can go, say, 10 miles in urban traffic without a disengagement, the improvements from then on (as measured by disengagements) improve dramatically, up until you get to the point where it's really hard to discover new edge cases. Waymo in 2016 was at 1 disengagement every 5000 miles, and that's a 4x improvement over 2015.
