Vehicle: Road: Sign
polarized road signs   (+3, -2)  [vote for, against]
minimize extraneous information with polarized light filters.

If one created a road sign with different messages at different polarities, people could tune to their preferred language by adjusting the filter on their end - could be either a polarized windshield or sunglasses as long as the angle is adjustable.

Also could be used to opt out of billboards such as the tampon adverts.

Could be very benefitical if widely used in this age of "visual data inflation".

Wouldn't this only give you two different signs? Any other polarisations would just give a mix of the two....

Although I like the idea of opting out of certain ads...
