What keeps the exhaust fumes out of the cabin when the fan isn't cranked up? Do you die on the first long drive on a nice day where you don't have the fan on? What happens if the interior windows are just cracked, or the sun roof? Seriously, dropping dead is a poor trade off for possibly saving 0.1 MPG.
