#21: Projected Road Markings on the Snow
I live in a place that gets pretty snowy in the winters, and driving in it is always a bit scary. Not only is there the possibility of sliding on slick ground or getting stuck in deep snow, but if the road is covered, you can’t even see any of the lines or other markings.
Leave it to Scandinavia, the land of the ice and snow, to figure out a way to help. If you can’t see markings under the snow, why not put the markings on top of the snow? It would be too hard and expensive to do it for every marking, but at least some of the really important ones will be more visible this way.
