The blister can be shaped to optimally, the bubble is shaped according to the airflow and the pressure... like a raindrop, which people think is "teardrop" shaped, but in reality is not aerodynamic at all.

I think one ought to compare the sizes of those two entities before getting carried away.

We know it's enough force to matter because cars designed to be as aerodynamic as possible have a shallow windshield and a steep hood to the point that they're nearly the same, eliminating any bubble.
