And car companies have so many more data-collecting opportunities than other products and apps we use – more than even smart devices in our homes or the cell phones we take wherever we go. They can collect personal information from how you interact with your car, the connected services you use in your car, the car’s app (which provides a gateway to information on your phone), and can gather even more information about you from third party sources like Sirius XM or Google Maps. It’s a mess. The ways that car companies collect and share your data are so vast and complicated that we wrote an entire piece on how that works. The gist is: they can collect super intimate information about you – from your medical information, your genetic information, to your “sex life” (seriously), to how fast you drive, where you drive, and what songs you play in your car – in huge quantities. They then use it to invent more data about you through “inferences” about things like your intelligence, abilities, and interests.
