Seems like the curse of the 80/20 rule. Cars that can drive themselves, monitor their surroundings using cameras, react to unpredictable moving obstacles etc are pretty impressive. That's the 80%. The other 20% is about things like bad weather (especially snow, which can completely cover road markings and signs) and "no win" situations. It's not hard to see a close-enough-to-perfect system taking the other 80% of the time.
