Many rural driveways curve sharply or meet the road where visibility is nearly zero. Instead of relying on pricey sensors or roadside mirrors, one inventive homeowner turned to basic physics. Inside the wooden tower, two angled mirrors work just like a submarine periscope: one at the top catches the view of oncoming traffic, the other reflects it downward onto a glass panel at driver height. Without electricity, cameras, or cables, it lets drivers see both directions before pulling out — a perfect fusion of simplicity and safety born from necessity, not design committees.
