There was some interesting comment a few months ago about the "human error" aspect of crashes. Basically saying that the quoted statistic (90% or whatever) is a way to NOT look at how road design contributes to the error. Earlier on this threat, someone commented that a road marked as 50 mph often has cars driving 150 mph on it, because it is a shortcut which is build like a racetrack. Obviously 150mph in a 50mph zone is human error, but a few simple changes to road design could take away the 150mph attractiveness of this road. Or see some of the articles on stroads, or badly placed left turns, etc. FSD might be a step to better road safety, but a focus on designing roads for safety might also be a good step.
