Those of us who don't live in cities have been driving fine at night without streetlights forever. No special paint needed. Cars have headlights.
I'm guessing you don't actually live anywhere that has serious wear and tear on their roads, otherwise you'd know that by the time half the winter is over that the paint is already worn down to the point where it's useless. And of course, if it's raining good luck on seeing those lines at all. Luckily HID lamps have helped with this, but don't get stuck driving on any Canadian highway anywhere between the months of: January(sometimes if it's really bad, this can hit as early as early November) through June when there is: Snow, rain, slush, mud, slop, dirt, or less than 50% sunlight.
And don't count on the shoulders to be a guide, because we don't really use them in most cases. Though if you're driving on a major highway like the 400 series(401,402,403,etc), some parts of the Trans-Canada, and a few other busy highways, we do have rumble strips.
