> As far as I understand from Tesla's progress, they need to merely cover ever more corner cases to go up the levels.
I think this is the crux of the disagreements here. You say they need to merely cover more corner cases, while I think many (including myself) think that this endless list of corner cases is the primary almost-insurmountable problem.
From what I've seen of Tesla FSD (and competitors), these systems do pretty well in highly structured and orderly environments during clear desert weather. In order to deal with chaos in a blizzard etc, we're going to need far more than just a few tweaks. At this point, none of these companies are even doing any testing in extreme environments. They're still trying to stop their cars from hitting pedestrians in well lit areas on known crossing points. [1]
