When returning home we opened the sunroof to cool the car down quickly
Wouldn’t AC cool it down quicker? And more efficiently at autobahn speeds anyway, drag is worse than running AC at speed.
I don’t disagree with you on the horribleness of the controls though. Worst part is, MB has gone the same route. I’ve got the last generation with physical HVAC buttons. I have no idea what my next car will be, but apparently Mercedes doesn’t want me to buy their cars anymore. Mazda has come out as anti-touchscreen, which I admire, but it’s going to be a hell of an adjustment in terms of suspension and drivetrain comfort.
