Anyone know? Think of all the energy wasted and light pollution created by street lighting while cars drive around with lights of their own. My very crude estimate has Chambana spending about $2M/yr on it. I know sidewalk lighting is important, especially in densely populated areas to cut down on crime, but the streets themselves? I've read some arguments saying it helps drivers see hazards or signs easier but, if that were so valuable, why are offramps lighted and not the whole interstate? Why not just improve headlights and technologies to allow for improved environmental awareness like nightvision.
Could help save $, aesthetics, and the environment.
