I'm writing this because the software is already there. There are decent alternatives to most things, sometimes multiple. What isn't there is government adoption, and commercial adoption.
Also, large companies offer quite robust support, deals to implement specific features, compliance with different regulations, etc. I know from experience that one thing I like about dealing with large entities is that they have many corner cases already figured out.
If you really want to have your foot in both worlds, you can always live the two-phone lifestyle. Might go that way myself eventually.
but that's just how it is, choosing free, ethical software is choosing a life of austerity and alienation.
I bet your Subaru is probably hackable, all these things run Linux under the hood, wouldn't be surprised if there were already a group of people on Reddit that have already done it. Lonely, this lifestyle does not have to be.
Years ago I would have said “much more likely to be QNX since a car always has a RTOS.” These days it’s likely Android Automotive, which has a massive share now. Note: despite the name it has nothing to do with “Android Auto.”
Overall, hacking on a car, even infotainment, seems very difficult. They really don’t want you to have any control over it.
While in theory that works, in practice I bear just iPhone all the time. With Android on the shelf most of its time. I even started to turn off its Wi-Fi so it keeps being alive after a week of being untouched.
