We can’t ignore core usability and basic safety issues by saying “on average, this is better.” End users can’t be expected to know that they’ll probably be fine, but an edge case they don’t understand will kill them one evening when they drive past a stopped ambulance.

Why not? If it saves 30,000 lives per year is that not a meaningful improvement? I suspect my understanding/acceptance of "unknown risk while driving" is flawed in some way, or at least very different from the general populace.
