he’s describing conditions that exist for every area in the world that actually experiences winter!

Snow (maybe not a foot but enough to at least cover the lane markings), black ice and sand drifts people experience every day in the normal course of driving, so it's reasonable to expect driverless cars to be able to handle them. Forest fires, tsunamis, lava flows, and tornados are weather emergencies. I think it's a little more reasonable to not have expectations for driverless cars in those situations.

Humans do drive when there's tornadoes. I can't count the hundreds of videos I've seen on TV over the decades of people driving home from work and seeing a tornado.

I notice you conveniently left off "foot of snow" from your critique. Something that is perfectly ordinary "condition where humans actually drive."

Many years, millions of Americans evacuate ahead of hurricanes. Does that not count?

I, and hundreds of thousands of other people, have lived in places where sand drifts across roads are a thing. Also, sandstorms, dense fog, snert, ice storms, dust devils, and hundreds of other conditions in which "humans actually can [and do] drive."

FSD is like AI: Picking the low-hanging fruit and calling it a "win."
