Writes Chris Sullivan:

For all these new safety devices to work, cars need to spy on drivers. Before I researched this, I didn’t realize that they already do.

The Mozilla Foundation reports that car makers “Collect things like your age, gender, ethnicity, driver’s license number, your purchase history and tendencies.” Nissan and Kia “collect information about your sex life.”

How? Cars aim video cameras at passengers. Other devices listen to conversations and intercept text messages.

Then, says Mozilla, 76% of the car companies “sell your data.”
