I'll believe that when I see it. Try using autonomous driving in the snow and get back to me. Nothing they've presented or have even talked about being on the roadmap solves the issue.

I also saw the car starting to break free (i.e. start a sideways slide) just as they clipped to another scene; that's what I want to see more of. It's an unavoidable occurrence in winter driving conditions, and the proper recovery to those is the most important skill to learn to drive on snow.
I saw thin layer of ice appear on parking sensors after few minutes of driving in snowy conditions, triggering "close object" warnings. And cars get dirty all the time, I wonder if cars will end up with separate wiper for each sensor.
And yet we're still limited to scraping blades made from rubber over tempered glass with the help of a bit of liquid cleaner...
Given how bug guts require a good bit of manual scrubbing to clear off a windshield and the cumulative impact of rock impacts, I'm not convinced they'll stay clear for any meaningful amount of time - at least not on a commuter vehicle timescale.
Heated glass will help, but it's not a guaranteed thing; ask anyone with a rear window defroster how long it takes to clear ice and snow off.
I live 5 miles outside of the nearest town and frequently have to drive long before a plow hits the road and long before it has warmed up enough for blacktop to be visible. That video doesn't even prove they can handle ACTUAL conditions when it's snowing in anything but the most ideal situation and at a speed that would require me spending 4 hours to get to work.
I mean... it's better than nothing but it's definitely not something that changes my mind on it being ridiculous to think that's replacing a human driver anytime soon.
