Why wouldn't a model that knows how to drive in winter-conditions be better than one that doesn't? There are more effective actions than hitting the brakes and hoping for the best available, one of which is to continue driving the vehicle in a manner that is compatible with the conditions. Don't make abrupt changes to the configuration of the car and search for traction and positive outcomes. Of course this is greatly simplified by not going 90mph on all-year tires.
