While I agree with the sentiment, I have accepted that the simple way to make “things” work now is to leverage the cheap computing that is ubiquitous. That headunit is likely now built on a SoC or some embedded OS and is easier and cheaper because of it.
Functionally we need regulations and safeguards in place that maintain the accountability for making the choice to use and build an OS as a life safety device that also serves Bluetooth audio. If the cost of supporting it, or failing to properly develop it, then perhaps the choice to make it dumb will become more adopted. Other economic forces are more likely to play out, but it’s a possibility that we can reinforce by what we buy and signal.
This is a decent video explaining some of the background on why polling got worse from business insider. Essentially it has more to do with conservatives being underreported (they don’t like talking to pollsters) then Gen Z, Millennials, or Gen Xs. Not saying that didn’t play a part, but Nate Silver has talked about this as well in his Silver Bulletin.
