"Per the initial discussion, there are places (and this is one) where a human is still MUCH better at assessing the situation and acting appropriately." You've done nothing to support that assertion. "MUCH better at assessing the situation and acting appropriately" doesn't compensate for 10x slower reaction time. Nor does it account for the high percentage of time that humans are paying attention to something besides driving. Machine systems don't get distracted, at least. We'll agree to disagree, but anticipate fully autonomous cars sooner rather than later. ;-)
