Because you generally want to shield from a flattish \ line of

We're talking about cycling caps, not baseball caps. A cycling cap
bill's curve would shade the center of the field of view while
allowing peripheral vision.

True. Just use what works best for you, short of Yehuda Moon style.

LOL.

Just like the curved cutoff in the awful OculuStvzo engineering
sample doesn't work...

There's no equivalence between the shape of the brim and the shape
of the cutoff. The cutoff is designed to manage outgoing light,
keeping it where it is useful and not shining it where it is not.

Not functionally equivalent, of course. You did see the video he
linked?

I did not, having no interest in or need for his product.

There are only two choices with a reversed crescent cutoff: Either aim
it low enough that it does not glare directly opposing traffic, or aim
it high enough to keep the 90 and 270 degree fields of vision for fast
curves.

Reversed crescent meaning the arc is oriented with the high point on top
or below?

black-tinted rear window; auto-dimming mirrors; manure-spreading
trailer.

I have an auto-dimming mirror in my new car. It verges on useless
as it does not dim anywhere near enough. I'd rather have a manual
mirror so that I don't have to reach up and point the damned mirror
at the ceiling so that I'm not blinded by the vehicle behind me.

My wife's small Honda has a manual tab on the bottom of the mirror.
Flick it with your finger and the "guy behind"'s lights are focused
on the ceiling :-)

Still leaves the side mirrors vulnerable. Okay, so the trailer will
need to be wide enough to block the view, but not as wide as to
require the mounting of extra side mirrors on the Honda.
