Even though this is "just reading the privacy policy", it's pretty damning when your car company says they can collect your sexual orientation, political affiliation, etc. and straight up say that they sell your information.

>we need a real, detailed analysis of what is actually collected, when it is collected, and where it is stored

Unless the companies themselves divulge that information, or various governments team up and force them to, this is the best you're going to get.
