Yes... and the Open architecture simply causes an Air overflow that exceeds the air fresheners capacity to "freshen" enough to prevent it from performing the task of "freshening" to an acceptable degree.
Within a closed space the size of a car's interior, the particles of freshness will be able to perform the task of "freshening" the air molecules, which consists of catching them and cleaning them off. After cleaning, each particle of freshness deposits a signature upon the air molecule. This is what tickles our olfactory nerves when we smell the freshened particles, thus the kind of signature they leave behind determines the freshness scent. In any case, having the freshening module within a car with the top off reduces it's effectiveness; each particle of freshness goes off into the world, pulled by the wind, cleaning a few air molecules but then turning into a tiny clod of dirt that thus falls to the ground, and will be ridiculed by the air molecules above for eternity,
"look at him, he can't even fly,"
"well no duh, he's a piece of dirt! Don't be such an airhead!"
The dirt beneath him, thusly perturbed, exclaim
"he ain't no piece o' dirt, he just a varmint particle that ain't fit nowhere, none of thems comes around here without the dirt knowin"
the air replies,
"well, he looks like dirt up here, you non-flying crap clods."
the dirt, annoyed:
"some of us are crap clods, but that doesn't mean you can treat us all like dirt!"
Thus started the bickering of the Air and dirt that has gone on since the very first vehicle left the factory with that "new car smell"...
