[FITrunner]

My parents are all about the friggin home shopping network and those "as seen on tv ads". They bought one of those solar car fan/vent things that hang on to your window when you leave them cracked open and the blow the hot air out of your car. They actually do work (a little). He's got two that he uses on his Lexus. I borrowed them to test it on my Fit. However I realized that my windows are tinted too dark for the solar panel to get enough juice.

Oh yeah one thing I did notice, is that if its really hot, say in the 90's, they do absolutely zero in my honest opinion. Because at those temps I usually dont sit in an idle car long enough to actually measure if they are helping or not, hot is hot. I get moving to get a breeze going ASAP or I turn on the AC. If anything they help keep the air circulating, so maaaybe its not stale. Other than that, its a novelty item.
