Well, in terms of death rate, I neither agree nor disagree with you. There is a sum total of one death involving a fully autonomous vehicle (and we don't know the full circumstances of that death). For you to infer a "death rate" is so presumptuous that it can't be taken seriously. There was bound to be a death at some point, but if it had happened after the number of miles driven had been double, would you calculate the rate to be half of what it currently is. You can't do statistics with a sample size of one.
In any event, the death did occur, and we can learn from it ("we" meaning those who have access to the full details), but we won't learn anything from the "death rate".
The point that I was making was that at this point of time, the average pedestrian, or even the average person, has virtually zero exposure to autonomous automobiles. You should of course avoid stepping out into the street into oncoming traffic. But it's not because of autonomous traffic. The real danger to you right now is human drivers. And arguably, by the time the exposure rate to autonomous traffic becomes significant, and the number of incidents like this grow to something that is statistically significant, the autonomous traffic will be far more sophisticated, and safer than it is now. Human-driven traffic may also be safer, thanks to some of the autonomous technology finding its way into human-driven vehicles (human driven, but autonomous braking when needed), but it's highly unlikely that humans themselves will be safer.
