What is Connected Car Privacy?
The privacy risks created by modern vehicles that collect and transmit vast amounts of data — including location history, driving behavior, cabin conversations, biometric data, and even your weight.
Also known as: Vehicle Data Privacy, Car Surveillance, Automotive Privacy
Your car is one of the most invasive surveillance devices you own — and unlike your phone, you can't turn it off while driving.
What Modern Cars Collect
A 2023 Mozilla Foundation study found that every major car brand (25 tested) failed basic privacy standards. Cars collect:
- Location: GPS tracking, often transmitted continuously to the manufacturer
- Driving behavior: Speed, braking, acceleration, steering patterns
- Voice recordings: Microphones for voice assistants capture cabin conversations
- Camera footage: Interior and exterior cameras (Tesla records cabin video)
- Biometric data: Seat sensors (weight), facial recognition (driver monitoring), heart rate (some models)
- Connected phone data: Contacts, call logs, messages synced via Bluetooth/CarPlay/Android Auto
- Media habits: What you listen to, radio stations, podcasts
- Passenger information: Number of passengers, seating positions
- Diagnostic data: Engine status, battery health, maintenance needs
Who Gets the Data
- Manufacturers: GM, Ford, Toyota, Tesla, etc. — all collect and store vehicle data
- Insurance companies: Progressive, Allstate, and others offer "telematics" discounts in exchange for driving data. GM was caught selling driving data to insurers without clear consumer consent.
- Law enforcement: Can obtain data with warrants (or sometimes without)
- Data brokers: Vehicle data is sold to marketers and analytics companies
- Dealerships: Have access to connected vehicle data
- App developers: Third-party car apps access vehicle data via manufacturer APIs
Real-World Examples
- GM sold driver behavior data to LexisNexis, which sold it to insurance companies — causing rate increases
- Tesla employees shared private customer camera footage internally
- Nissan privacy policy allows collection of "sexual activity" data
- Hyundai/Kia privacy policy permits sharing data with "affiliates" and "business partners"
- Police have obtained months of location data from car manufacturers via warrants
How to Protect Your Car Privacy
- Read the privacy policy before buying — Mozilla's "Privacy Not Included" rates car brands
- Don't connect your phone via Bluetooth if possible — Use a separate aux cable for audio
- Opt out of telematics — Contact your manufacturer to disable data transmission (not always possible)
- Decline insurance telematics programs — The discount isn't worth the surveillance
- Factory reset rental cars — Delete your phone data from rental vehicle infotainment systems
- Buy older vehicles — Pre-2015 cars have significantly less connected technology
- Disable OnStar/connected services — If you don't use them, turn them off
- Support right-to-repair legislation that gives consumers control over vehicle data
