EFF – (and Opt Out of Sharing When You Can): “Cars collect a lot of our personal data, and car companies disclose a lot of that data to third parties.

If you’re curious about what your car knows about you, you might be able to find out. In some cases, you may even be able to opt out of some of that sharing of data…A car (and its app, if you installed one on your phone) can collect all sorts of data in the background with and without you realizing it. This in turn may be shared for a wide variety of purposes, including advertising and risk-assessment for insurance companies. The list of data collected is long and dependent on the car’s make, model, and trim.  But if you look through any car maker’s privacy policy, you’ll see some trends:..Without a national law that puts privacy first, there is little that most people can do to stop this sort of data sharing. Moreover, the steps above clearly require far too much effort for most people to take.
