Drivers are always learning new things about their cars thanks to the internet. A car salesman posted a video explaining the hidden features most owners are completely unaware of.<\/p>\n

Ever wondered what those little black dots on your car’s windscreen are for? One Reddit user did, and the answer is quite fascinating.<\/p>\n

According to Autoglaze, these dots, known as dot matrices, help distribute temperature evenly to reduce optical distortion or lensing. “This happens when the frit band (the solid black one) heats up much faster than the windscreen’s glass, creating an optical distortion that makes either straight lines look curved or bowed inwards toward the centre.”<\/p>\n

The dots also help “preserve the urethane sealant used to bond the glass to the frame”, ensuring your windscreen stays firmly in place.<\/p>\n

<\/p>\n

The experts add: “They serve as a contact point between the glass and car frame. They create etches on the surface, making them rougher so the adhesive can stick better to the glass.”<\/p>\n

“Frits are also there for aesthetic purposes. If you look closely, the contrast between the dark band and the transparent glass can look too obvious even when viewed from afar.<\/p>\n

“Creating a halftone pattern or dot-matrix allows a gradual decrease in size, making the transition much more subtle and easier on the eyes.”<\/p>\n

One Reddit user was amazed by this, saying: ” That is brilliant and simple. So simple that it isn’t believable but so believable that it can’t be that simple!”<\/p>\n

Another user asked: “Ok, that makes sense. But why is it on the windshield, rear windshield, and quarter glass, but not on the operable windows?” A third user exclaimed: “I am stunned at the amount that I have learned about frit today.”<\/p>\n
