These windshield dots have a function

Explained at the whatdoesthismean subreddit:

Those little black dots on your car’s windshield are called frits. They are printed on the glass using baked-on ceramic paint and serve several important purposes: Secure the Glass: The solid black band and the dots provide a rougher, etched surface for the urethane glue to bond the windshield to the car frame. Protect the Adhesive: The solid black border acts as a shield to block harmful UV rays from degrading the glue and keeping it strong over time. Regulate Heat: The dots decrease in size as they move away from the solid black band. This creates a gradient that absorbs and distributes heat evenly, preventing the glass from warping, cracking, or suffering from optical distortion when it gets hot in the sun. Reduce Glare: They diffuse harsh sunlight so you don't experience intense contrast between the dark frame and clear glass.
