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 would gladly gladly keep my AC, heat, hazards, blinkers, wipers, maybe a few other buttons and that's it. I don't need back cameras, lane assist, etc.
I find it hard to believe it's cheaper to have all the cameras, chips, and other digital affordances rather than a small number of analog buttons and functions.
You should check how SW and HW are tested in the car.
A typical SW test is: Requirement: SW must drive a motor if voltage reaches 5 V. A typical SW test is: Increase the voltage to 5 V, see that the motor moves.
Now what happenes at 20 V is left as an exercise for the user.
