i wouldn't consider glow in the dark paint a new invention, but it's a good idea to put it on roads, even if using the headlights on your car would make it completely useless
if it lasts long enough to be practical its at least an improvement since in my experience glow in the dark paint stays light for a very short period of time, i remember every halloween recharging my mask under a black light (incidentally black light charges up glow in the dark stuff like superfast)
looks kinda pretty i guess
