How much can this damn' data be worth in order to risk the loyalty of people paying tens of thousands of dollars on your product? I assume the _actual_ profit they are making are in "addons" and extras that can be unlocked remotely.
All automakers have to do is require access to that data for features, like maps, traffic updates, or entertainment.
I hate the idea of in-car advertising, and I don't like the thought my data being sold. But I do give up some privacy for functionality. My biggest annoyance with my car is I don't have Android Auto for the maps, I use google maps when driving, and video from my ADAS is used as training data.
