Selecting the temperature can be done on the wheel, or with a single press on the screen in a predictable spot.
Same with media: play, stop, volume, next, previous.
Other adjustments, yes, those may need a modal interaction. Much like physical dials. I would slightly prefer physical dials, but not something I would need to adjust during drives almost ever, so I don’t see a problem here.
I don’t know about recent ones, but in old ones you need to long press the wheel to get a menu to select what it controls, then select a mode, then adjust the temp.
And the media controls are a mess that changes periodically with updates.
