I wonder how well these cars handle heavy snowfall or ice on the roads. I know firsthand how driving becomes infinitely more complicated under these conditions and it would be major selling point for these cars if they could handle it smoothly.
They don't handle snow at all yet. There is no question that will be quite a hurdle to cross, but I doubt it will be for the reasons most think. My guess is figuring out where the road is at is going to be the hardest part; where I bet most people think it is "how do I drive on ice". Without impatient, jacked-up-4x4 drivers driving a twice what conditions warrant, it is just a slightly different calculation of static and dynamic frictions.
