The ones where I'd be most interested in the videos were the ones where the Waymo was stopped/slow/preparing for a turn and got hit in the back (4, 10, 12, 14). While likely the fault of the human driver, hesitant/unexpected behavior by the Waymo could have contributed to those. Three consisted of the Waymo hitting random objects - not catastrophic but clearly shows weaknesses in the self-driving: 3 (Waymo ran over a traffic cone), 17 (Waymo hit a "free swinging parking lot barrier arm"), 18 (Waymo hit a shopping cart). Ten of the accidents seem unavoidable for the Waymo and clearly someone else's fault: 1 - distracted driver rear-ends Waymo coming to a stop, with a delta-v of 20 mph. A 0.2 g deceleration could be a bit faster than normal but definitely isn't slamming the brakes, and the report mentions at one point that the other driver was using a phone. 2, 5, 6, 8, 9, 11, 13, 19 - someone hits a stationary Waymo in a parking lot or while getting out of a parking spot. [Edit: Someone pointed out that these could be preventable for the Waymo, if it knew how to use the horn. https://news.ycombinator.com/item?id=34974313 https://news.ycombinator.com/item?id=34974313] 16 - Garbage truck tried to squeeze by a stopped Waymo, didn't fit (although for this one, it is possible that a human driver would have pulled over further). Two were emergency braking situations - would be interesting to see what the reaction time was and how it compared with a human driver: 7 - someone cut off a Waymo and got rear ended 20 - Waymo hit a minibike that had crashed and tumbled into its lane, despite braking. And of course there has to be a weird one, 15 - Wind blew debris into Waymo. Overall, it seems like the report mostly avoids assigning fault, which is a good thing - in the end, how many crashes happen matters more than who was at fault. [Edit: and as the "use the horn" example shows, even when the other side is clearly at fault, improvements may be possible]
