i agree. i've driven in Minnesota, Wisconsin, and Northwest New York (Lake Effect Snow!). in the winter in particular i've always driven with the external air
on to avoid the fogging. it's recycled 2x, once when u breathe it and then when your car runs it through again. u know how u can blow on glass and create a moment of fog? that's what you're breathing into the re-circulated air. if your heater can't effectively heat outside air, u have a problem with Toyota imo.

every car i've driven requires that u keep the defrost on in colder climates.

every car i've ever driven (without heated mirrors) requires that i scrape the frost off of the mirrors if i expect to use them in a cold climate. even then there have been situations in which the ice/snow is thick enough where the the heated mirror melts the ice making contact with the mirror and the shell of ice is still blocking the view of the mirror.

Arkansas! Just "north" enough to throw you southern drivers off when the cold comes! ;) I've got in-laws in Oklahoma and Arkansas and just came back from the holidays over there.

edit: just read the whole thread, sorry to be redundant! :D
