Lexus human interface issues and climate control discussion
For example, if you go and drive a new Land Cruiser, to change the manual air speed, you have two-step process (1. hit the CLIMATE, then 2 change your speed) but you can still change the air flow with a hard buttom
Contrast that to the new LS500, you can change the air speed, but you need to go all remote touch to change the air flow
Or the ES, you can change both the air flow, and the air speed, but you cannot turn off the AC
The most bewildering, poorly thought out design among the Lexus brand, for those who like using AUTO, all the power to you.
I have no idea how the UX works, I am afraid to look.
It seems like you do.

Its literally one button to get to a screen where you can turn the A/C off in my LS. I don't see what the big deal is.
I understand that you want more control, but the system isn't designed to easily give you that control, nor are the majority of other vehicles auto HVAC systems. They want you to just let the system do its thing, and most people consider that a feature they've paid extra for...thats why carmakers put that system in their cars.

You simply have a preference here that is not typical. I would suggest that you simply use this as a criteria when you are shopping for cars instead of calling cars that aren't designed the way you want them to be designed a poor design. I and many, many others are very happy with our Toyota/Lexus auto climate control systems...we aren't wrong.

you're the one who keeps trying to make this personal towards me, not the other way around.The bottom line of this is that every vehicle has a different approach to their controls. Owning and regularly driving cars from different brands has shown me that. When you get accustomed to those differences, they really aren't a big deal. I can give you a list of things that I think are better implemented in Chrysler's controls than in Lexus' controls and vice versa. That doesn't mean that I can't use the controls in either vehicle, I certainly can. As you have said before, your parents never liked that ES...so they should get rid of it and get something they like. It doesn't mean the ES is a bad car or poorly designed, they just didn't like it. They could have set it so the HVAC screen was always on the nav screen, or on half the nav screen as thats an option for the ES and all of those controls would have been right there.
Once you get used to the controls in any vehicle...its just not a big deal.
Yeah doesn't make sense to me either. In the Pacifica when I press the A/C button it overrides AUTO.
In my 4Runner, it tells you for best results, when heating, turn on AUTO and turn off A/C. Same for manual operation.

And the point is, to ‘warm up the car’ i wouldn’t matter if it’s on 9c, 19c, or 29c as far as how quickly it will warm up.

By turning A/C off when you are in AUTO, you are turning off the "full" auto; the system will still determine the "optimal" fan speed and vent setting, but you are overriding the system's ability to also determine whether to turn on/off the A/C compressor.
It's like when I ignore my Waze directions because I feel like I know better than Waze does....
Lexus User Interface
The only thing that really lets the whole thing down and would stop me from buying one – it’s the infotainment system. It’s painful to use and lacks any ingenuity. Using it on the move is hard and the mousepad style system for navigating the menus is inaccurate and fiddly. If Lexus was to invest in a decent infotainment system, they would literally own this segment, because they’ve done everything else to a high level of style, function and form.
