“Private” is not a word many would use to describe a home that's located at eye-level to a busy monorail hub.

But one line in South Korea took a small step toward making it a little tougher for passengers to peep into nearby homes on their commute.

Reddit user Isaac Sung recently shared photos of a self-tinting window on the forum. The idea is that whenever they pass a private residence, the train windows will automatically fog, making it impossible for passengers to look into nearby homes. It's not just a "light fogging," either. Check out the before and after shots to see.

If only all public forms of transportation could be so considerate.
