Dunno, I think of the people that follow other cars as sheep. In my subaru I can pick any lane I like, and often the one with the least travel has the best traction. With snow tires and a subaru I can handle just about any conditions up to where the snow lifts up the car off the tires.... which I've had happen. Digging compressed snow out from under a car is no fun. So often I see a giant line of cars behind the plow, slipping and sliding along, then I pick the deepest snow lane with the most fresh snow and it's just fine. Generally it's not the lane you pick, but the safe speed for that lane. Sure that might vary per lane, but with today's sensors and electric motors the autonomous driver should be more accurate at quantifying that than a human. After all a computer could easily say apply 50HP to each wheel (one at a time) for 10ms or similar to quantify where the dynamic/static threshold is.
