Calling B.S. on that one. No matter what the testing nerds proved / disproved on TV or the internet. I worked as a design engineer in automotive. I did A/C audits, testing, etc as part of my tenure at Hyundai-Kia. I also did direct physical, dynamic in car testing too on controlled test tracks. But we can all choose what we want to believe, so I don't expect you to change your belief. Nor am I calling or insinuating any inferiority on your part, or superiority on my part. Just saying I've been there and experienced much automotive engineering research. (I say these things because I don't want to fight / argue or rub anyone the wrong way. I just want peace in my life.)
And besides, I specifically put down both left sides, and leave the right sides closed. It doesn't rearrange the stuff on the interior (as much) done this way, and doesn't buffet in my left ear either. Nor does it create the amount of drag of putting all the windows down. And is more comfortable than with all the windows down.
Unless it's blame hot (that's a southern technical measurement), I suggest you try both left side windows. It's wonderful. I tend to close the windows on the interstates though, as I don't care for all the noise. I use the A/C as needed with the windows up.
Peace be unto us.
