So that's not how it works. I don't think it works. That is, I don't see any way that it can reflect a different percentage of oncoming-headlights glare than of other kinds of things you want to be able to see.

It almost looks like a beam splitter. Aside from the practicality of this device, can anyone explain how it could work? It almost looks like a beam splitter.
