May be hard to explain.
We have had a bunch of snow recently at this point the main roads are cleared but pretty much covered in a fine layer of salt as it’s all been crushed.
I was wearing my Shady Rays Pro Polarized sunglasses (if the type of polarization matters).
While going on a stretch of roadway I travel all the time wearing these glasses. The road looked to be a light grey color while looking through the windshield. One would expect this as the roadway is normally a darker grey then with a light layer of crushed salt would give light grey.
I then looked in my rear view mirror and the roadway in the mirror was nearly pure white, looked to be covered in fresh snow honestly.
I looked in my side view mirrors and the roadway behind me was pure bright white as well. So I took off my sunglasses and sure enough the roadway was as bright pure white like looking in the mirrors. I dropped my sunglasses back on and went back to grey in front of me but stayed bright white in the mirrors.
I wear polarized glasses frequently and while they crisp up color and vision I have not seen such a drastic change in the color of something simply by putting on the glasses.
Also I have never noticed such a drastic difference in something simply by looking in the mirrors with glasses on compared to not looking in the mirror.

Hopefully that makes sense.

I don’t think so. A reflection of polarized light is still polarized.

Not exactly sure what's going on, but it may have something to do with the fact that reflected light is already polarized, while direct light is non-polarized or very weakly polarized.

When you place two polarized pieces of glass on top of each other the polarizing effect can appear to disappear or intensify depending on the angle of the polarization of the two pieces. If you held your glasses in front of your eyes and rotated them 90° I bet you see something different.

Very simplified example of the quantum phenomenon of polarized lenses.

You experienced a glitch in the matrix.

You need to cock your head the other way.

This and the refraction through the layers of the windshield may also come in to play.

Playing with polarizing film can be entertaining. It's kinda cool when repolarizing an LCD display or restoring a panel from the '80s.
