One accident is clearly not one data point. If Uber had driven a billion miles with 0 accidents, we would safely conclude they were safer than human drivers with "0 data points". Assuming that accidents are independent, we can model this as a Poisson point process. If the accident rate is 1 per 100M miles and Uber has driven 3M miles, the probability of there being zero accidents in that time is P{n=0} = ((λt)^n / n!) * e^(-λt), where λ=1/100M and t=3M. Doing the math, it seems that's 97.04%. So, yes. It is possible that Uber's accident rate is 1 in 100 million. If so, this incident would fall in that remaining 3%. It's unlikely, but possible. |

One thing we can say about the woman killed the other day by an autonomous Uber, is that unlike the other ~40,000 killed on America's roads over the past year, her's was not in vain.
Every day that we delay the widespread deployment of this technology, it's another 100 or so people dead. Of course, the public is unlikely to see it that way. They see one death as a tragedy, but 40,000 is just a statistic, business as usual, nothing to get excited about.
