^^Bc people from Texas & Arkansas (for example) that don't get much in the way of prolonged cold or snow say things like AS are more than enough on my uber capable CX5 its really just ice that's the issue. I say spend a winter where it goes below 0F frequently, 200" of snow is not unheard of and they're hilly windy roads everywhere..then tell me how your AS are plenty good enough in all but icy conditions. Does everyone need them where the temperature goes below 40..no but that's about where the benefits start and grow pretty much exponentially from there as the temperature drops and terrain gets more challenging.
