This is obviously more useful for those that live in a hot location. As I'm in north Texas, and my office parking lot is vast and exposed, I would find this exceptionally useful, it's something I (manually) do every day in my current car. When arriving at the office, I'd like the car to determine the forecasted high temp for the day, and whether it is currently raining. If the high is expected to exceed 90f (configurable), and it's not currently raining, I'd like it to present me the option to vent the hot air. Perhaps it can pop up a dialog box when I'm at a standstill in my office parking lot, based on geo-fencing. If I choose to use te feature, I'd like the car to tilt the sunroof, and crack all the windows by about 1/2 inch. If it starts to rain (it'll know that from the rain sensor for the wipers), then I'd like it to close everything up, and let me know via a push notification to my cellphone. the purpose of this is to keep the cabin temperature 'reasonable'. I realize we could run the AC as well, but the point is to keep the ambient temperature a little lower without using power, so that when we do start the AC ready for the drive home, it doesn't have to work quite as hard. My parking lot is relatively safe, but others might want the option to not crack the windows.
