That is a useful data point. Extremely optimistic bystanders think self driving cars will lower death rates to zero.
Statistically about 7 people die on the public roads per billion passenger miles. At half a million miles, assuming the miles are statistically random and indistinguishable from the entire country (sure, summer in socal is as hard driving as a winter in a blizzard at night in Montana, sure...) then 424331 death free miles means that technologies death record is no worse than 336 times worse than human drivers, at least so far. Perhaps its only 335 times more deadly than human drivers. Even drunk people aren't that dangerous.
Or in other words, the self driving car can be summarized to lots of predictions based on very little data.
