Did they use a BMW? LOL
I have noticed that my car seems optimised for side windows up.
Bmw went to all the trouble to make that fancy little spoiler pop up in front of the sun roof, yet did not seem to do squat about the side windows, the buffetting ad the lack of cover on the seatbelt riser makes it NOISY as all hell at highway speed. I find that on vent with the sunroof in popup mode I'm the most comfortable.
I heard a great line from the engineer who designed the Audi diesel for the lemans races.
"Noise is energy, if you get rid of noise you save energy."
My little bonzai run is not a scientific test by any means, but what it proved to me was that It does not make enough difference for me to care....
Damn the dinosaurs full steam ahead... !!
