even if you have not gotten into your car for several days, the warmer air inside of the car is attempting to travel through the medium with the least resistance...glass in this case. since the warm air is escaping, it is attempting to bring with it the moisture it contains, the warm air escapes leaving only the moisture behind.
Gee, for all these years, I thought glass was a vapour barrier
