Even notwithstanding that you discovered the rack "rails" aren't perfectly parallel, it's not completely true.

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).
