Suppose I am in my car driving down the road and my evap blows it's
guts out. If I am a person with any sense at all, I roll down the
window, and I can guarantee you, I do not pas out. Now, if I am
setting at a red light and the same thing happens, if I sit in the car
long enough to pass out I am 1)very stupid and 2) such a waste of
matter in the universe that my passing will not matter.

Like I said, a window down at 60 mph will do plenty of "stirring".
Give me a break and go do a radon test on you're home.
