I suspect the outliers that confound machines will also frequently confound human drivers, so a lot of that is a wash. The only way to remotely look at this meaningfully is in aggregate. Deaths and losses per million trip-miles. This is where the momentum will come from. There will be a day where machines reach and surpass the human level, and we'll see a huge momentum towards penalty-boxing human drivers. I fully expect to call Progressive in 2040 and the hologram Flo will tell me that it costs four times as much to insure me if I have the audacity to retain a steering wheel. I also think there's a snowball factor. Self-driving cars are going to be way more consistent and predictable than human drivers. That only amplifies as more and more vehicles on the road are self-driving. Once you get to 90% self-driving, I could imagine things like increasing speed limits and dynamically organizing convoys for efficiency.
