SuperCruise seems to be worse than Autopilot at crash avoidance, at 7:20 in the video (where a car veers into his lane and he has to take evasive action while the SuperCruise just goes merrily along). Autopilot would likely have braked for that, as I had similar situations happen to me. Also a good reason to keep your hands on or near the wheel with SuperCruise:
I don't think braking would necessarily have prevented that accident. It looks like the car was going to side hit the other car. I would not trust AP to handle that. I would have taken over on AP just to be safe.
Supercruise does handle the merging lane better than AP earlier in the video. Supercruise does not try to center in the wider lane like AP does.
Also keep in mind that Supercruise is L2 so the driver is still expected to monitor and be ready to take over. It just let's the driver keep their hands near the wheel rather than require physical hands on wheel.
I don't think AP handles every case better than SC or SC handles every case better than AP. I am sure each handle some things better and some things worse. They are different systems with pros and cons.
