The problem with places that have real winters is that lanes migrate. They are not absolutely positioned. Nor are the sides of the road edges which may project well out into the street and parked cars even further. No road markings visible. Humans make their own lanes. This situation can happen for many weeks-long periods in a typical winter in, say, Minneapolis or Buffalo suburbs.
If a self-driving car does the right thing staying "in lane" while all the human drivers do the wrong thing flocking to new emergent paths (which swing back and forth across the "lanes"), then the self-driving car is wrong and dangerous. I'm not talking about when it's actively snowing either. I mean the snow on the ground just remaining there, covering things.
It's not about dealing with slippage or skill driving, it's about complete lack of context markers. I don't think any current or near future self-driving solution can adapt to this.
That's fair and I've certainly experienced this where I live, which is north of Buffalo in latitude. Also frost heaves are no joke in non-city/non-highway roads and present another obstacle to FSD. I guess my point, if I had one, is I would hope FSD would be programmed to be as conservative as possible in adversarial winter conditions and not overreact to such conditions and that alone is enough to increase safety because humans, for various reasons, are not conservative enough. Hard to imagine for sure.
