    With light in the cabin, you have reflections in the windshield. It’s easier to look through glass when your side is dark. That’s the premise behind “one-way” mirrors. In a police show, the interrogation room is brightly lit and accentuates the reflection of the glass. The investigators on the other side of the mirror are in the dark and thus able to see clearly through their side.
