Even colder

whilst driving home... 'twas cold, out of shot is the snow flake to warn me the outside temp is low. The car even tells me when I start, low outside temp. Thing is, I still can't really see the point of this. Yes it is interesting, but does it make the blindest bit of difference.... um not really. I guess when it hits below zero this will help with freezing roads etc. It is quite fancy, my car.
