My 2004 Fiat Stilo has dedicated buttons and no single touch screen. The "board computer" is a 5 "pages" menu that is able to adjust simple things like dashboard lighting and disable my door light, that's it. I never have to search for anything and, even more important, don't have to take my eyes off the road to adjust heating, radio, etc.
I searched for 'iife javascript' and although it understood what I was searching for, it's 3 code examples only showed an iife on the 3rd code example. the 2nd one didn't make sense at all [0]
What's next? Touch screen gear shifting? Touch screen horn? It's dumb IMHO.
