Maybe because its burning hot out and people need high AC to cool down. Or the opposite in cold weather. Or to defrost windshield/rear window. Climate control

Climate control is a great feature. But it's not perfect, and there are instances where you need to manually override. Just because you don't run into them doesn't mean they don't exist.
EDIT: BTW on cars with physical controls all of these things are either button press or dial turn away. I've never had to look at the controls to do these things.
- vel0city 4y agoSo here's an example. It's over 100F outside, my car is probably 115F inside it at the moment. Setting my car to 70F inside instead of it's current 72F won't make it cool any faster. Even setting it to it's "LO" setting won't make it cool any faster. The AC compressor is either on or off. The car will set the fan speed to it's best possible speed to cool the car as fast as it can regardless of it being 72 or 70 or 68. Me adjusting things manually won't make the compressor work harder or make the car cool faster. There's zero benefit for me to touch the AC controls. The car knows it's hot. The car knows how I want it. It will do what it can to get it to that target temp. Me doing anything will just result in more distraction away from actually driving the car.
- kipchak 4y agoWouldn'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.
- kipchak 4y agoPerhaps it depends on complexity of the system? I like in Florida and have to do some tuning occasionally, but I think it just has a typical in cabin and ambient sensor and isn't aware of how much sunlight there is.
- vel0city 4y agoIf it has a screen it probably knows how bright it is as it can probably change between night and day modes. 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.
- _carbyau_ 4y agoAlternately, I don't care about he speed of change. That blazing sun shining on you via radiation directly feels different than if the sky is overcast. I want to easily tweak the temp to account for my personal comfort. I don't care about the temp of the air except as an input to helping me be comfortable. I don't want to have to start and then sit in my car idling to wait until it gets to temp only to find out I want a little more or less.
- vel0city 4y agoI don't experience much difference. Low emissivity tinting does wonders to make you more comfortable. I even have glass roofs on my cars and it really doesn't make that much of a difference in comfort in my car. On top of that, my cars also know how intense the sun is. It wouldn't surprise me if that's also an input to the climate control.
- _carbyau_ 4y agoI have a 10+ year old car. I don't expect to update it until 2030 at least. I guess I'll get to try out this tech then.
