Is there evidence that fancy looking screens don't show better in the showroom than legacy looking knobs and buttons? Where under use, they may be better, I am not sure all that sells better.
All I know is personal anecdotes from people I talk to. I know a couple people who have a Mercedes EQS - they've all said the same thing: the big screen is cool for a little bit, then it's just annoying.
I think it will take a generation or two of cars before some consumers start holding back on purchases because of this. For now, they don't know better. But I'm sure after owning a car and being pissed off at it, they'll think a little bit harder on their next purchase. I think consumers are highly impacted by these types of things - small cuts that aren't bad, per se, but are annoying. Consumers are emotional, they hold grudges, they get pissed off.
I sort of feel the same way about fix-a-flat kits. Once people actually have the experience of trying to use a fix-a-flat kit, they'll start asking car salesmen if the car comes with a spare...
