Or I'm in the car locked and loaded

Will the deer be glow in the dark as well?

While the street is cool this is the real public service:

That's cool

So what happens when the paint gets dirty

The same thing that happens to regular paint on highways?

Not really, being dirty would effect the paints absorbing rate which in turn make it have less "energy" during the night to glow. Than if it is dirty the dirt will make the glow very minimal. The point for it is to glow. Go get a glow stick and roll it around in brake dust and dirt and see how much it glows afterward. It's a cool idea but I don't see it providing too much light for driving after a while

How would it work if it was overcast most of the day and the stripes did not absorb enough energy to stay light for 8 hours?

---

It is "charged" by UV light which is not stopped by the clouds, so an overcast day wont make any difference. Its like the lume on a watch on a much larger scale-

this seems like something that should have come out a long time ago. pretty cool

It did. Some state like Wyoming where a lot of trucking accidents happened painted their highways with luminescent paint that was more visible at night. Then the feds threatened to pull highway funding bc it wasn't uniform and they had to change it back.
