Keep in mind that a billion miles is a very small number in this context. People in the U.S. alone drive well over 3 trillion miles every year [1]. We simply don't have enough data yet to say that autonomous vehicles are safer.

- slg 8y agoI completely agree and should have put something about sample size in that comment. However there are no red flags yet in the statistics and I think that is important. Think of it like flipping a coin. We decide to flip a coin 4 times and get 2 heads and 2 tails. That wouldn't be enough to draw any meaningful conclusions about whether the coin is fair or if it is weighted to one side, but I would feel a lot better about that result than if the coin ended up on the same side 4 times.
