Why not make something simple and practical? Something small so they can get more bang for their recycled carbon buck. I think we should make those little road dividers that seem to fall apart and get removed with the snow plows every year. Do they make opaque carbon fiber. We could fill them with something that changes color when there is black ice on or near them. Save some lives. If they are that sturdy and hold up to the weather then they can be reused if they are scraped off of the roads Plus we all know how the government loves to spend money on anything overpriced. The Department of Transportation would be in hog heaven
