And my point is that a large percentage of the people in the US, not just those in Wisconsin, live in places with ice and snow. Unless by "places like Wisconsin" you meant to include the entire northern half of the US (which is why I commented that you lived in California too long). My point about the performance of a heavy car (4,647 lbs curb weight) also applies to rain-slick streets.
While a large percentage of families with cars have more than one, it's generally one per licensed driver or less. In a two-car, two-commuter family it makes things more difficult. But since not too many people can afford a car which costs $100K+ in its extended-range version, I guess you are correct that anybody who can afford it can also afford a conventionally-fueled SUV for bad-weather days.
BTW, the S Model starts at around 50k. There are choices of models and prices, like most all other vehicles.
