For whatever reason, the idea of this being in my car is relatively scarier for me than if this was just my phone ?

I think partially as my mental model of both android auto and CarPlay is that they operate as a passthrough of my device rather than as an separate installation of the OS entirely (I wasn’t aware the head unit itself had the ability to install APKs independently).

Also, feel like John Gruber is going to have a field day with this one
