Re: Volvo's good deed -- In contrast, Edward Land (the Polaroid camera guy) came up with a system for polarizing car headlights and windshields to lessen glare from oncoming headlights in 1948. Apparently, none of the car manufacturers implemented it because there was nothing to gain financially from such a safety feature. https://www.polarization.com/land/land.html https://www.polarization.com/land/land.html
