I have never owned a car but have connected my phone to car systems too many times. My assumption is — when you do that via an Apple CarPlay enabled console you are guaranteed a level of privacy as well, isn’t it? I know cars do not have Internet connection on their own but what stops them from making you install an app on your phone that would handle all these connections (BT profile work etc) and then upload whatever they want to their servers.
