What's the deal? You always smirk when you pass a car going down the road with all the windows fogged up; You notice how they have the defroster going full blast and just a little hole to look out of? Yeah, so what does that have to do with it? They always have an old Bernie, Hillary or Obama bumper sticker, think they are so smart while everyone else is a moron, but can't even read the owners manual to know you don't put the heater on recirculate.
