> What do you mean, you don't want "software"? Where do you draw the line? A basic digital wristwatch has "software".
I think this nomenclature is a result of the post-Jobs software as "app" paradigm + Web as the definitive "application" platform era.
The majority of software written, especially in these circles, is going to be some sort of user interface/CRUD stuff. The "invisible" (and frankly remarkable, when talking of things like ECUs and ABS software) is basically like The Earth (it's just always been there and taken for granted).
You're going to have software for a modern, efficient car, whether you like it or not. For the engine (fuel injection alone needs a bunch of software), ABS, traction control, A/C, and countless other things. And whether your radio has physical buttons or not, unless that physical button is on a radio from the 1980s and directly controls a variable capacitor and a belt to a frequency indicator, it's going to have software.
Of course we had cars entirely without software, about 50 years ago. But they were slow, had many quirks, and absolutely massive relative fuel consumption compared to today.
