Was walking the dogs at five am when I realized the impracticality of this statement. You are suggesting people wear sunglasses at night so automobile drivers don’t have to slow down to a speed safe for the conditions. Just don’t overdrive your headlights so you can safely see and react to anything (cyclists, pedestrians, livestock, rhythm pigs, critters in the road)
Also retrofitting all front and back windshields of all existing vehicles on the road.
I believe you’ve veered into possible but far from practical territory.
