Of the fatal car accidents that I know some of the details, apportioning blame probably wasn't going to be a factor as they were on a highway. A couple have been just straight distracted driving... And one was teenager poor decision/risk reward analysis for a pass.... I'm sure none involved expected to have a chance of a major crash in the moments before it happened.
I do see people in town driving a bit aggressively, but nearly all of those accidents aren't major.
We have no fault insurance here which I think kind of looks at accident details, but if you keep on getting in more than your share of fender benders, you will pay more regardless of fault...
The more I think about it, its really the highways that need automated driving first, in terms of saving lives. Implement some sort of "slot car" system with a wire in the pavement or metal plates or something, and have some simple over the air communications between local cars or simple radar to detect how far away the next car is. I think the tech is available now to do this, but getting everyone to agree on standards and designing the right system the first time is tough, then actually building the infrastructure would be cost a bit, and having the system handle human drivers in the mix is more complicated.
IMO there's no technology barrier, just the public isn't ready for it yet.
