Hidden interface controls that affect usability

I drive a Toyota that is nearly old enough to run for US Senator. Every control in the car is visible, clearly labeled and is distinct to the touch - at all times. The action isn't impeded by routine activity or maintenance (ex:battery change).

Because it can be trivially duplicated, this is minimally capable engineering. Yet automakers everywhere lack even this level of competence. By reasonable measure, they are poor at their job.

I'm sympathetic , but think it's a disservice to the designers to present it like that:

> Every control in the car is visible

No. And that would be horrible.

Every control _critically needed while driving_ is visible and accessible. Controls that matter less can be smaller and more convoluted, or straight hidden.

The levers to adjust seat high and positions are hidden while still accessible. The latch to open the car good can (should ?) be less accessible and can be harder to find.

There are a myriad of subtle and opinionated choices to make the interface efficient. There's nothing trivial or really "simple" about that design process, and IMHO brushing over that is part of what leads us to the current situation where car makers just ignore these considerations.
