  Sure, but the goal isn't "perfect", it's merely to do better than human drivers. Human drivers make that mistake constantly, so the case you're describing is one where the cars will do MUCH BETTER than people because cars are better at sharing information over time. So we go from a world in which every driver independently has to update their own personal worldview and is thus individually surprised by the addition of a new sign to one in which a few cars are surprised and have to slow down and update but within a few days every subsequent car through the intersection automatically knows the new data.

    I really think this is key. Cars letting other cars learn from their experience. Although that too has limits, for example if my car detects a cat in the road that wasn't there before it probably doesn't need to propagate that information.

  "The wrong decision" is very unlikely to be "drive into a ditch." If a stop sign disappears, the car won't figure "gee, I guess I can plow on through." If a stop sign shows up, the car is very likely to still notice it, and if not it still will be paying attention to what other cars are doing. It won't plow into the car in front of it. It will still notice what cars on side streets are doing.
