No I have never pressure tested taking off the wipers. I was primarily referring to how stupid it is from a safety perspective.

Safety is a personal, and weather-driven, decision. You could compare with window[s] up and down.

On a closed course. To falsify it.

I have not pressure tested but I have tuft tested the windshield, A-pillar and side window. The tufts at the base of the windshield flow forward down into the cabin intake even with the ventilation fan off and the “recirculation” button pressed. The wipers are inside a high pressure/low velocity bubble. Nothing to be gained by removal of wipers on my car.

Except perhaps a tiny bit of weight.

I pulled the rear wiper, motor, washer nozzle, tubes and wires from my Insight. It didn't do much at clearing snow, and removal of the motor made the (at the time) weak hatch struts lift the hatch far more easily. With weight, a penny saved is a penny earned. Oh, and maybe it caused a tenth of a percent in drag reduction. I didn't measure.
