I was thinking the same thing. I would think they thought to write in some traction detection, however I've never seen a demonstration of the like. They need to test cars in the heart of MN during the winter; when you can't see the lines on the road, and sometimes the car in front of you.
or simply slow down. I dread to have to sit in the car that decided to just stop, risking freezing. You don’t know if you sit there for an hour, a day, a week?
