I would think it would be a combination of the two. If it is just due to autosteer, what is it doing better than a human to reduce frontal impacts? This seems to suggest that the humans wreck more often when making lane changes or making evasive maneuvers.

Or humans aren’t quick or alert enough to make the evasive maneuvers made by Autosteer. The NHTSA made a simple study based on airbag deployments on cars that had Autosteer installed. There was a 40% decrease in deployments. My understanding is that these cars already had Traffic Aware Cruise Control installed.
You seem to be making any and all possible logical contortions to avoid giving Autosteer any credit.
