Eye Detection and Eye Detection AF

You can set eye detection of nothing, but the camera will not do it.
However you can set eye detection of a car, and it will find eyes of people.

I think you mean Auto mode? The R6 II has it, so if not, I'd expect a firmware update to add it at some point.

That's interesting. And what I found. must have a subject for eye detection. So makes it more difficult to set on buttons for an easy on/off.

Since it's not just an on/off, yes. But you can keep it on and just toggle the subject, if you like.

One of these instant AF mode change functions, maybe?

Per the R5 Manual;

Subject:

"None": "The camera determines the main subject automatically from the subject information detected."

"Note": You can choose the following subjects by pressing the shutter button halfway. In scenes without relevant subjects, the camera tracks other objects:

People: People, animals, vehicles

Animals: People, animals

Vehicles: People, vehicles

The manual for the R3 says the same.
Perhaps that's what they mean already, but it would have made more sense if the priorities were like this:

People: People, animals, vehicles

Animals: Animals, people

Vehicles: Vehicles, people
