I live in Wisconsin. There are tons of deer here. I know wherefore I speak when I say, if you think that deer are all easily visible, you’re Just-Worlding, or kidding yourself. They’re not always looking at you; sometimes oncoming headlights hide them. Sometimes the road curves, and your headlights don’t illuminate them until the last second. Somehow, drivers don’t see them, and there are always roadkill deer on the side of the highway every few miles in season.

But that reminds me of a creature that drivers talk about in near-mysterious terms— black ice. That is usually visible, if you slow down enough to pay attention. It looks like wet pavement.

Just sayin’, it’s not a bad idea to be visible when walking, but the person engaging in the inherently dangerous activity (driving) has the moral responsibility should something bad happen. It also happens to be a good idea to slow down and not overdrive your headlights.

(My college roommate’s brother died that way.)
