I use it all the time in the hot weather. If imagine that they don’t put auto up for the same reason they don’t put auto up rear windows, kids. I remember being a kid and I had my head out the window (we were in the driveway, just got home) and my mother started to roll the windows up and didn’t notice I had my head out. I started to yell and mom noticed lol. Granted, they could have pressure sensors that if they detected more than normal resistance, they would go back down, like a garage door.
