As a disclaimer, the three iPhones I've ever purchased have all been used. I keep them for as long as possible. I don't use iCloud. I don't buy apps. In fact, I don't give Apple any money as far as I know.
I wish a Linux phone was a viable option but they are years away from being truly usable and decades away from any hope of mass integration with cars.
android isn't linux-y enough to be able to use android auto on a more typical linux kernel?
