This is what symbolic AI skeptics in the 90's dismissed as 'brittle' solutions. You engineer an AI system, then find it fails under some unforeseen situation. You fix for that situation and find it fails under some other unforeseen situation. I was driving on the highway the other day and there was a large black object ahead in my lane. I was about to take evasive action when the object shifted slightly. The motion was enough for my brain to sense it was a lightweight object (not a human fallen on the road) and a further movement in a puff of wind to establish it was an empty garbage bag rolling on the highway. No need for evasive action. On the other hand if I had seen other debris/leaves tumbling in the wind but the black object was stationary my brain would have sensed it as a potentially heavy object and taken evasive action. I remain skeptical that we can if-then-else engineer our way to self-driving until cars have the common sense adaptive behavior that humans have.
