I went to the '39 and '40 fairs. I think it was in 1940 that i saw a
polarized polarized travel travel film at the Canadian exhibit. Instantly
sold. Took the polarizers home a made a polarizer for my microscope. I
was 11 at the time. Much older before I took Realist format slides.

The headlight glare application would have been neat. Idea is to put crossed
polaroids on the windshield and on the headlights; incoming headlights are
dimmed lots, but your light on the road gets depolarized and you can see
well. Story is GM scotched it just after WW2, because it would have 
required brighter lights, and they weren't ready to go to 12 volt batteries
yet.
