> I'm not sure how manually "blasting cold" to keep raw meat in the back cold also doesn't freeze you in the front, or what that has to do with auto mode, but we typically don't have groceries in the car for more than about 20 minutes and don't worry about it. I know people who have a much longer trip to get groceries and they use a plug-in cooler; that seems like a more sensible option.
Ofc you can have a cooler, but that eats up space, and not all grocery trips are planned. Re 20 min - sounds like you are lucky - if you get into a traffic jam you might get stuck.
How it helps - not a universal feature but you can often adjust heat/cool for back/front, I've also seen it where each seat gets their own climate control knobs.
Regarding MAX - that's nice, but that's not auto, which was my point.
And yeah glasses definitely help - I love my transitions for that reason. But display tech matters here - glossy vs matted, and in my experience glossy holds up a bit better under sun while matted holds up better to e.g. night city driving. Backlights are important too - but again to my point this is all overcomplicated and a knob is just easier/cheaper/less prone to breakage.
It's nice you have an auto mode that 'works great' but as you admit there are a fair number of cars where that's just not true. I suspect in part that's because this is a difficult problem, that is partly self mfg. And I don't think most people at dealerships have time to test it to the degree you seem to have (although you didn't mention how it handles in open air, i.e. with sunroof or retractable hood) - a knob is something I can test in 5 min and know it "just works".
