Winter Wonders

So I tend to have random curious thoughts regarding the way things are created. Such as, why are the road stripes (the dotted lines or solid lines separating road lanes) painted white? Now I do realize maybe when roads were first paved and completed white may have been one of the only colors of paint available to use; however with modern advanced technology why can't they now use fluorescent green or orange. I mean come on- have you ever driven in snow and tried to find/stay in your own lane! It's almost impossible with the road lines being white. Try driving in a region that has snow 6 months out of the year. It stinks! It seems to me some smart person would realize this and start grandfathering in a new more vibrant color on the roads that you would be able to see when it snows. Hey, it's not like the roads in these regions don't need to be fixed yearly!
