Snow tires are not new to BMW's. Here is something from Bavaria. Enjoy.

I feel more confident in my rear-wheel drive BMW with snow tires than I did in my Cherokee XJ with all-terrain tires and 4x4. Especially in situations where there isn't lots of deep snow where ground clearance is an advantage (a foot+ of snow). The 50/50 weight distribution of the car along with good traction control really helps. A lot of trucks and SUVs are just garbage in the snow because they are too light in the back. My friend's Silverado won't go anywhere in the snow unless it's in 4x4. Sometimes it even looses traction in the rain.
I won't be driving my Wrangler in the snow, but I can imagine it would be slightly worse than the XJ with similar weight distribution but a shorter wheel base.
Numerous European countries have similar laws. It is also cultural thing. Even before these laws becoming specific, it was tradition that you have two sets of tires.
And... they advocate for snow chains also, on top the mandated winter tires, as conditions require. Maybe they know something about snow chains that North Americans don't.
Ie.... If you have a good set of winter tires, you don't need snow chains.
I'd like to see your explanation why you feel 4WD stops better in snow/ice.
I've seen a lot of videos from professional studies of winter tires vs all season and 2wd vs AWD. All of them show the same thing. The only thing that improves stopping power is better traction , that is tires or chains. AWD does nothing for reducing stopping distance. I haven't seen anything that compares 2WD vs 4WD in winter conditions.
Technically correct. About the only advantage of AWD vs regular is that those cars weight more. More weight, better traction on the same footprint. Although more weight usually translates to longer stopping distances. But if traction isn't optimal, it's possible to get better traction and shorter stopping distances. Would have to run some tests to see if that plays out as expected.
Exactly what I was asking. With ABS, wouldn't that negate the factor that is claimed in this video?
I'm not a Jeep guy, so not sure. What generation are these Jeeps? They look late '90's to early 2000 to me. But not sure.
I remember reading in the mid 80s, I think it was, Audi that stating in the deep snow cars stopped better with ABS off. Built a wedge of snow under the tires. I believe in a lot of conditions ABS means longer braking distances, but allows straight line braking and the ability to turn and maintain control.
I think you have it the other way around. In most conditions, ABS leads to shorter stopping distances as it's the coefficient of static friction vs kinetic friction. Static friction leads to shorter stopping distances. The snow plow effect on a locked wheel is one of the rare instances where you get shorter stopping distances.
I've explained it before, please use the search feature.
And unscientific utubes mean less than nothing.

Their advice was not to exceed 50 km/ hr when using chains. That’s 30 mph. Not for me, thanks.
Technically wrong.
So you drive more than 30 mph in the snow and ice?
You realize you’re talking to a Canadian.
You drive faster in the snow and ice so you can get to Tim Horton's faster?You’re realize you’re talking to a Canadian.
