If you have the resources to do blind studies (not to mention double-blind studies), then please do so. I suspect, however, that you will say that you don't have the time. That's what I meant.
Frankly, in these situations blind studies aren't done. Popular Mechanics, Consumer Reports, Car and Driver don't do blind studies. They do easily replicable tests and publish their results for people to judge and peers to examine, and possibly retest.
However, if you do have the resources, please test it yourself. Keep in mind that a proper scientific test requires a random sampling of the available population (meaning
both cars
and drivers). If you can also get a dust-free wind tunnel, then that's even better. Keep us updated on your progress.
