Wouldn't it engage a heavier fan speed if there was a smaller disparity in temperature? For example if it's 75 in the car and I'd like it to be 72 turning the AC down to 70 would engage a heavier fan speed with the downside of increased noise, so practically I would cool down quicker by setting it to 70
and could then adjust back up to 72.
But more practically, if I start catching a lot of sun from the window I might want to go from 72 to 70 to compensate, even if the cabin temperature is more or less the same.
- vel0city 4y agoThe car knows how intense the sun is. It has sensors to measure that. Coupled with some decent low emissive tint it's really not hard for it to handle such an idea. I live in Texas. I assure you I live in an area with high heat and intense sun. My cars have glass roofs. My cars seem to handle it fine.

If it can tell it's bright, it can guess you're getting more radiant heating. It's been like that on every car with a screen built in that I've owned, more than a decade of model years.
