They look beautiful, but they could also save a lot on streetlight power.
Like 5 years ago goesbyjones had to listen to my complain on a drive home about the road lines only being reflective instead of glow in the dark. Considering the glow in the dark paint, I was always curious why they couldn’t paint those lines with that, but then I wondered if it was the composition of the paint that would make it unfeasible. And then my dear sister pointed out to me that I was analyzing the paint of lines on the road. Reality check.
