As pointed out, it's Adaptive Cruise Control or what Tesla calls TACC. Basically it's cruise control that slows down or brakes for cars in front. This is basically the only mode that would still be working with a radar car if there was low/no visibility (Autosteer obviously can't, given radar can't detect lane lines).What is ACC?
I'm arguing in this narrow circumstance, you wouldn't be safe using ACC either (I certainly wouldn't), and it likely wouldn't have helped in the given pileup example. It may give you false confidence to go at higher speeds, when there are serious limitations (like the classic example of where the target car in front changes lane, revealing a stationary car in front; most ACC systems will plow right into the stationary car, given the radar is typically tuned to ignore stationary objects).
