Why does the glass coating improve the visibility on a rainy day?

Glass may look smooth, but it is actually a rough surface that attracts water, so when raindrops fall on it, they spread out unevenly and distort light from the scene beyond the glass.

Glass coatings can coat the surface with a smooth layer of water repellent molecules that cause the water to bead up into droplets, which are then blown away quickly by the wind.
