The structure works like a simple periscope. A mirror near the top captures the view of the road, while another mirror redirects that image downward to a viewing panel at driver height.
There are no cameras, sensors, batteries, or electronics involved. The system relies entirely on mirrors and reflected light, allowing drivers to check for approaching vehicles before pulling farther into the road.
The unusual design later attracted attention online because such a difficult visibility problem was solved with basic physics instead of advanced technology. The article presents it as an example of how simple ideas can sometimes be the most practical.
