>> People are terrible at driving in fog and snow and ice

They are considerably better than the AI systems who currently just stop and say "I see no road" or facetiously stick to markings/signs that mean little during winter conditions. The last time I rented an SUV (2020 Jeep grand Cherokee) it wouldn't let me reverse into a parking spot because the rear camera/sensor was caked in snow/ice. In order to be dangerous at winter driving you must first be able to actually move.

There's a line of can't/won't/shouldn't here though. The AI systems probably could drive in these conditions. Most of them utilize GPS to navigate. But they don't because that's a high risk activity. I'm not totally convinced that even now, the average accident rate of a self driving car wouldn't be lower in adverse conditions compared to a random driver- if the car were just told to do its best and let loose.

Not that I'm advocating this is a good idea.
