To clarify, I was referring to visibility of deer and items. The situations you mention here limit the vision of the driver as a whole, and then the visibility of things no longer matters. Where I live we also have lots of deer, but accidents involving deer & other bigger wildlife is uncommon enough to make the local news (and you'll almost never see such roadkill along the roads). During the season I'll see animals several times per week, sometimes having to stop more than once on a single drive.

Nastiest run in I've had was where a group of deer had gotten in between the wildlife fencing on a stretch of highway

Illustration regarding visibility.

It looks like wet pavement.

That's the part that makes black ice nasty. The temps can be slightly above freezing with wet spots everywhere. Then suddenly one small spot has slightly lower temperature. Bam, black ice.

I agree that drivers have a much larger responsibility, barring reckless behaviour. What I disagree with is driving being inherently dangerous. It's a question of system design. As you mentioned Wisconsin, I assume you live in the US. My condolences.
