the let-in-fresh-air mode is for countries where there's plenty
of country side and fresh air, it's also necessary so that drivers
can be more alert.
however under spore road conditions, we can only breathe in other's
exhaust, so it shd be in recirculate mode. either way it will cause
drowsiness due to stale air or carbon monoxide, i would rather
breathe recirculated air than exhaust smoke. but, lucky for
marchies, we have the plasmacluster!!
anyway for the elegance with auto climate control, the default is
recirculation.
when you choose to let in outside air, sure got vapour (ala
"smoke") cos of the different temp between the two airs, its
common. but again, i would advise recirculation, only change to let
in outside air occassionally when ther's no exhaust outside to
exchange for fresh air.
