There's a lot of anecdotal information IMO when it comes to tire discussion... And has a lot to do with manufactures CYA and creative marketing to sell more product. Are winter tires better? Yes, of course, especially with respect to snow/ice. But there's a lot of things to consider. Daily driver? How far? How is road clearing by you? Etc., etc., etc.
Last year I was late, and didn't even put my snows on because every single time, the shop was way too busy. And even getting caught in bad ice/snow storm, with my AS Pirelli's, the 330Xi had no trouble getting grip! This year, first frost, ice, an I got my Blizzaks on, lol.
Driver error IMO is responsible for 99% of issues in regard to weather. Speed, follow distance, what road traveled, etc., all contribute. In 40+ years of driving, I'd say there was maybe 2x that despite my efforts, the vehicle was in control, not me, lol. Just my thoughts
