In Design of Future Things, ex-Apple UX designer Don Norman interviews (anonymous) engineers of a self-driving car:

DN: "It sped up when we left the freeway instead of slowing down on the exit, that was dangerous. Why did that happen?"

ENG: "Car saw it was on a straightaway. We'll add a rule to handle that."

DN: "So you have to add rules for every possible situation? Doesn't that mean that the car is always at risk for what it doesn't know about yet?"

ENG: "That's Not-A-Problem. We will classify everything."
