Because these billboards are just monitors rotated 90 degrees, they’re invisible to polarized sunglasses. It’s like a real-life ad blocker!
@sandofsky With the added bonus of not being able to see your car console while driving because that is also a monitor now!

@Unabart @sandofsky thankfully I do not need a car. Lucky me.

BTW this reminds me of the movie They Live

@prefec2 @sandofsky
Love that movie! I wonder if there is some kind of paint that is invisible unless wearing polarized glasses
@Kjellhaften @prefec2 @sandofsky classic lcds have a polarized foil if you remove that you can only read the display with polarized glasses on.
