I think you misunderstood the point of my comment. If indeed it is an order of magnitude less deaths, then it probably doesn't matter if the demographics shift, but we actually have to see that change and know the demographics to actually know that. I'm just saying that we should pay attention, as we should with anything that has the capability to change per-capita figures for adverse actions, as to what is actually happening and not assume. That said, since we're already seeing an increase in these cars and the use of their autonomous options which match "self-driving" to greater or lesser degrees, I doubt we're going to see a 10x decrease before they are inthe wild, because to some degree they already are. I just want us to know what that means by looking at as much info as we can rather than a single metric.
