“According to Mozilla research, popular global brands — including BMW, Ford, Toyota, Tesla, Kia, and Subaru — can collect deeply personal data such as sexual activity, immigration status, race, facial expressions, weight, health and genetic information, and where you drive.

Researchers found data is being gathered by sensors, microphones, cameras, and the phones and devices drivers connect to their cars, as well as by car apps, company websites, dealerships, and vehicle telematics.

Brands can then share or sell this data to third parties. Car brands can also take much of this data and use it to develop inferences about a driver’s intelligence, abilities, characteristics, preferences, and more.”
