Why does rainwater pool into a shape of windshield wipers?

Question

I’m sitting in my car, it’s raining and wipers are off. However, I can clearly see how the droplets pool in a specific manner, reminiscent of wiper movements. Can someone explain the physics behind it?

Your wipers could also have a water repellent that gets applied as you use them. This causes the water to bead up and run off your windshield. The pattern is where the wipers apply it to your windshield regularly.
