This is the best summary I could come up with:

But drivers are given little or no control over the personal data their vehicles collect, researchers for the nonprofit Mozilla Foundation said Wednesday in their latest "Privacy Not Included" survey Security standards are also vague, a big concern given automakers' track record of susceptibility to hacking.

Cars scored worst for privacy among more than a dozen product categories -- including fitness trackers, reproductive-health apps, smart speakers and other connected home appliances -- that Mozilla has studied since 2017.

The absence of such a law lets connected devices and smartphones amass data for tailored ad targeting and other marketing -- while also raising the odds of massive information theft through cybersecurity breaches.

Japan-based Nissan astounded researchers with the level of honesty and detailed breakdowns of data collection its privacy notice provides, a stark contrast with Big Tech companies such as Facebook or Google.

Further, Nissan says it can share "inferences" drawn from the data to create profiles "reflecting the consumer's preferences, characteristics, psychological trends, predispositions, behaviour, attitudes, intelligence, abilities, and aptitudes."

If an owner opts out of data collection, Tesla's privacy notice says the company may not be able to notify drivers "in real time" of issues that could result in "reduced functionality, serious damage, or inoperability."
