That last point you made is exactly why I'm excited to have them for the first time. Turn the AC off, crack the windows and/or open the sunroof, crank the seat ventilation. I often like to have the windows down/sunroof open in nice weather but when it's that hot...
Hoping the seats will offset just enough.
Where do you live? I've lived in Florida, Arizona, and Texas (among many other places), and in none of those places have I ever enjoyed driving with the windows down in 100-degree weather. In Texas and Florida, the air is so stifling at that temperature, the last thing you want to do is have heavy air hitting your face at 60 miles an hour. And in Arizona, while the air is much drier, you can still feel the heat blasting you over and over. My windows don't come down unless it's less than 70 degrees.
I will have to disagree with
@BNeal, though, in that the ventilated seats on my 2019 Limited push out a lot of air... my *** gets cool in about 30 seconds.
