You're assuming Autopilot can't currently account for losing traction (this is probably true). But unexpectedly hitting a patch of black ice won't favor one model over the other - in either case you'll use the same methods to slow down. The only difference would be if you also had to avoid an object some distance ahead, and the drift model helped you maneuver around it by applying the throttle. It's extremely difficult for me to contrive a scenario where this would help avoid an accident over a standard traction control model found in any modern automobile. But technically I guess it's possible it could help.

> contrive a scenario pretty easy actually. car ahead swerve to avoid an obstacle. autopilot don't see the obstacle until the car ahead swerve. autopilot has to change lane to avoid obstacle. if it has recently snow some lane will have different traction than others. this is what happens on most of these pileup videos you see on youtube, so while not common (there are a handful a year after all) they aren't just hypoteticals

  You're right - I guess it's not that hard to imagine that scenario. But how would the car know which lanes have traction? If the car can reliably detect black ice it can avoid it without ever having to slip/skid.

    yeah that the hard part, humans can't identify it visually, so car will probably be able to identify it only after it loses traction, reducing the margins significantly.

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.
