I don't know why people love leather seats. Yeah, to me they are horrible. Freezing cold in the winter (though I guess heated seats fixes that, my leather seating car was the wife's and I rarely drove it) and burning hot in the summer.
If I run the AC on the windshield, yes, the outside fogs up because if it's 70% humidity outside we are all in heaven with how dry it is. I hate how depending on the adjustment, I can't not have the AC blowing on the windshield (I like the air coming out the vents and floor and have a variation of how much to each but if more goes to the floor, it also starts going to the windshield.) And it's boiling hot in the car from sitting in the sun, doesn't much matter what the temperature is outside. I run the AC when it's 60 out because of the car sitting in the sun all day and with the laid back windshields of cars today doesn't allow any air movement in the front seats and you sit in a pocket of hot air even with 4 windows down.
