Many of us know how bad modern cars are for privacy. Yet many of our friends and neighbors do not realize how intrusive it really is. I linked a blog entry from Mozilla’s investigation about car privacy. In that blog is a link to their make-by-make analysis. The amount of very intimate information a modern car collects is honestly appalling. It includes health data, real time mood information, weight gain or loss, and so on. And it does so even for passengers.

The web has many resources talking about this problem, but almost no resources on what to do about it. I know the simple thing is to say, “just drive an old car bro!” That’s fine if you can, but not everyone can. Also it has drawbacks like more maintenance. Sometimes less safety if it’s older than certain safety features. For the purpose of this thread, it is more interesting to focus on newer, surveillance enabled cars which are the majority of what people drive on the road today.

Some people have figured out how to bypass the surveillance package on some cars. One way is to uncouple the antenna it uses to phone home. Other times you can bypass the telematics module or remove a fuse that powers it. I feel like we really need a central model by model repository of information.

Past that, how do we prove it has worked, if we do it? Has anyone reading this tried to use an RF detector to see if their car is still trying to phone home, after they have bypassed telematics? What are your experiences? I want to buy one and use it to test my own car, but the info on the web seems sketch.
