Wiper delete rain trails

On my car in the rain yesterday, I reinstalled my driver's side front wiper blade, as I always do on the somewhat rare rainy or misty days here in coastal Southern California. This time, I mounted the arm as low into the cowl behind the hood as possible. I photographed how my rainy window behaved on the driver's side and the passenger side. In other, earlier reinstalls for rainy days, I had mounted the wiper arm at stock position and noticed the rain droplets on my rainX coated windows behaved very differently, with droplets sitting on the window behind and slightly above the wiper arm. This time, with the arm much lower, I observed that the rain drops on the wiper-less and wiper-installed sides behaved the same way. At speeds as high as 62 mph, the drops seemed to have the same size and density and ability to stay put on the windshield at the same heights.

The down side is a loss of some of the wiper blade's water clearing near the A-pillar on the driver's side.

If anyone is interested in the photo, I'll find the cables and upload from my phone.

My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

This cowl area is intentionally designed to be 'dead',to aid in fresh air cabin ventilation.
You'll see in smoke flow visualization images that the rest of the airflow just jumps over this stagnant area.

No need to undo the wiper delete; just go get a hitchhiker. And a broom.
