talking about cars that drive themselves only 99% of the time is a straw man. Waymo's disengagement rate in the year leading up to nov 2017 was once per 5,596 miles [1]. i'm not sure how to translate that to a percentage of time, but let's say a disengagement is a tenth of a mile - that means waymo's cars are self-driving 99.99998% of the time. they're the closest to market, but that was almost two years ago now, and in the 65 reported disengagements they didn't kill anybody. |

> Now it is important to note that the definition of a "disengagement event" may vary between companies. Most companies report every case in which a human grabs the wheel for any reason. Waymo (*) only reports the events, in which if not for the human intervention the car would actually cause a dangerous situation [read more here]. The way they do it, is for every physical disengagement they gather all the sensor data and next simulate multiple scenarios. If these scenarios lead to a dangerous situation, such event is being reported. According to Waymo in 2016 nine events would have lead to the car hitting an obstacle or another road user, approximately 1/10 of all disengagements they've reported (124). Hence there is such a gap between Waymo and the rest of the pack.
I also think it's hard to generalize from Waymo employees being attentive and general road users achieving the same thing.
