The proposition in question is whether Android Auto/CarPlay is “widely accepted,” so implicitly what I’m being asked to believe is that there is a large portion of car buyers who strongly prefer a car that supports these features but then don’t actually want to use them because of security concerns. I think the idea is absurd on its face.

Not sure where you're being asked to believe that beyond a single thread contribution. I've argued your point earlier in this thread and agree that they are "widely accepted", so you may be barking up the wrong tree.

Nevertheless, some people prefer not to accept them while not being entirely anti-tech either. You may not be agreeing with choices other people make, but it goes a little far to call them "absurd on its face", don't you think?
