Remember we live in a world of cross winds, so much of the time the racks present a larger surface area to the apparent wind and generate more drag than one might think at first.
That's the main reason I would encourage people to remove their entire rack if it's not regularly used (and not ridiculously difficult).

My roof rack get so much use, I would lost without. It's what allows my CRV to carry long loads (12 foot lumber, 10 foot rugs etc).
It looks pretty aero to my eye. Compared to my old square windsurfer rack, these things are great.. And compared to the ones I used back in the 70s that made that super loud humming sound, these are perfect!
I'm wondering about crosswinds. If a crosswind is hitting the side of the car,
90deg off the direction of travel, I can't understand how it will hurt MPG...
