I know wax makes water bead

But shouldn’t it fly off when you drive?

Stormed all evening. Stopped before I drove home. Those water bead withstood 50mph speeds. I’m impressed.

In my experience they’ll fly off if there aren’t any contaminates on the paint. Annoys me sometimes because when they dry they leave a million dirty spots.

Also, there is still the surface tension of the water to overcome, so if there isn't enough airflow to break the surface tension of the water to the surface of your car, it won't fly off. Aerodynamics plays a part, as it'll determine the boundary layer for flow. After the laminar flow separation, you'll get an increasingly larger boundary layer where the actual movement of air goes to nothing, and won't push the water off.

Depending on the shape of the hood, air can separate at the leading edge and might not reattach until 1/3 to 1/2 way of the windshield. This will cause a large zone of low surface speed, which might not be enough to move that water.
