This discussion misses an important consideration. I cannot back this up
with a study but I believe window screening tends to make the vehicle look
a bit ominous. I travel throughout the country on secondary roads and have
deliberately avoided installing window screening even though I know of the
positive cooling effects of screening.

I want people to be able to see into my van so that I look like I'm not
hiding anything. I do this because there's an unmistakeable climate of fear
in our country. Because I'm already an outsider relative to the local
citizens who see me, (and I'm usually travelling alone--I'm a man) I want
to appear as friendly as possible.

For the same reason and others, I remove my political bumper stickers when
I travel. Again, I want to appear friendly and accessible rather than
politically strident. I believe there's more to window screening than
cooling the interior of the vehicle.
