I really hope this isn't a trend that will lead to less physical knobs. IMO, physical HVAC controls should be with a physical knob and/or button.
Too late. My 2022 Audi A6 already is all touch screen, including the HVAC controls. Dash is completely screen-based as well, including the speedometer and tachometer/RPMs. Some of the technology is really neat, but some of it is a little too much. I wouldn't have minded less screens, more buttons, and a little more storage space like my old 2013 had.
