And a new study just illuminated how much data is coming from your car, and who's on the receiving end.

Northeastern researchers had to find and build clever ways to reroute Wi-Fi and cellular signals from the cars to their data collectors — same with the applications.

Between the cars and their apps, data was sent to several large companies: Alphabet (which owns Google), Amazon, Spotify, Microsoft, and Meta (which owns Facebook).

As for the apps' data, strange names to come up on the list included Pinterest, Reddit, Docusign, Dun & Bradstreet, and a software company called Press Ganey Forsta.

Manufacturers' other explanation for data sharing was that sharing was on the consumer.
