Mozilla released their studies, and I’m seeing a growing number of posts on the Internet about cars and the privacy nightmare they entail. I remember how this issue wasn’t talked about earlier because “just buy an older car” was still prevalent. I’m so happy that people are taking notice. Thank you to this community and Mozilla for the work they are putting in!
