That special layer in the windshield, what makes the HUD reflection perfectly visibla is probably the reason why we see the blue glare, when sunlight, that falls directly into the HUD, gets reflected by the HUD.
Has nothing to do with tint, since we don't have tiunted windows. Also BMW offers tinted windows AND HUD, what they wouldn't do, if there is a glare on the windshield then...

Looks like I have pull out the deadly scientific stuff.
The modern displays with LCD's work with polarized filters to allow the LC's to make a light or dark spot with an electric pulse. The HUD is an LCD image projected onto a reflective windscreen. If you wear sunglasses that are polarized, it kills the HUD image to nearly zero. If you tilt your head, the image returns because the polarization of the glasses no longer cancel the polarization of the display. So far, most of you know much of this physics.
Sunglasses are made for reducing glare from objects and water outdoors. The best results occur when the orientation of the polarizer is horizontal or close to that.
Ok, given that glare is horizontally polarized and polarized sunglasses are vertically polarized, why doesn't BMW vertically polarize the HUD so that we can wear our polarized sunglasses to eliminate glare AND still see the HUD?
