I'll just leave this here.
As was said before, these videos are made by people that sell tires. There's a reason they always do it on an ice rink or on top of a mountain vs. cold pavement. If you live somewhere where it doesn't snow, it just gets cold, then winter tires are 100% overkill. A tire like Continental DWS is the best of both worlds with it's blocky section. But I have never had any confidence driving on winter tires on cold, dry roads. Everything feels loose, spongy, and unresponsive. Not a good look for those of us in the south/midwest.
