Thanks for your response!
I believe you raise a very valid point here. At some point (for simplicity let's be agnostic about when this is) the net effect of AVs will be a reduction in accidents and injuries/deaths. Therefore, we don't need to be at zero AV-related accidents for allowing them on the roads to be desirable. As you say, we may se a decline in other accidents.
Two good examples could be what causes many of the worst accidents (where people are seriously injuried) - drunk driving and excessive speeding.
If I come across a bit skeptical, it is because I am. Not skeptical about the ability of the industry to innovate its way around technological challenges, but skeptical about the ability of legislators to keep up with the speed of innovation, and especially of federal and state governments to allocate the needed resources toward investing in appropriate infrastructure.
I appreciate your view, cheers!
