I really like to drive with the window open in nice weather. However, the Prius has a real bad behavior that causes a low frequency oscillation that hurts my ears. In order to reduce it I either have to put the window most of the way up or open up all windows. I was wondering if putting on the window deflectors would impact this behavior, possibly making it acceptable? Anyone with window deflectors care to comment?
I've noticed that occasionlly in different cars with different window configurations... try cracking the back windows and inch or two, then put the drivers window where ever you want. It seems to aleviate the problems for me. Also, someone suggested it on here a while back, but for higher speeds when you don't necissarily want all that wind hitting you in the face, you can crack the two back and one front window a few inches for excelent airflow, and none of it in your face!
I haven't driven a Prius without window deflectors, but I can assure you Bernoulli is still hard at work. Opening the windows only slightly reduces the effect, but doesn't eliminate it. Being able to open the windows a bit without letting the rain in is a nice feature.
