Car Tracking: 14 Ways Connected Vehicles Collect Data
Connected cars can collect your data in at least 14 distinct ways, ranging from GPS location and driving behavior to biometrics and voice recordings. This article explains each data collection method, how the data is used, and what you can do to protect your privacy.
How Connected Cars Collect Data
Modern vehicles are equipped with multiple sensors, cameras, and communication modules. These systems generate data that is transmitted to the manufacturer, dealership, or third-party service providers. The data is used for navigation, maintenance alerts, emergency services, and increasingly for insurance and marketing purposes. Here are the 14 primary ways your car collects data:
- GPS Location – Your car’s navigation system tracks your precise location, routes, and stops. This data is used for turn-by-turn directions, but also for traffic analysis and location-based services.
- Driving Behavior – Sensors monitor speed, acceleration, braking, and cornering. This can be used for usage-based insurance or to provide feedback on fuel efficiency.
- Vehicle Diagnostics – The onboard computer records engine performance, battery health, tire pressure, and other mechanical data. This helps with maintenance reminders and remote diagnostics.
- Infotainment Usage – Your interactions with the radio, touchscreen, and connected apps are logged. This includes music preferences, podcasts, and even contacts synced from your phone.
- Voice Commands – When you use voice assistants in the car, your commands may be recorded and transmitted to cloud servers for processing. Some systems store these recordings to improve accuracy.
- Smartphone Integration – Connecting your phone via Apple CarPlay or Android Auto can share your contacts, messages, and call history with the car’s system.
- Camera Data – Front and rear cameras capture video for parking assistance and safety features. Some vehicles also use cameras for driver monitoring, which can track eye movement and head position.
- Bluetooth and Wi-Fi – The car’s wireless systems can detect nearby devices, potentially logging their unique identifiers. This is used for features like automatic unlocking or to improve connectivity.
- Emergency Call Systems – Systems like eCall automatically send crash data, including location and severity, to emergency services after an accident.
- Remote Access Apps – If you use a smartphone app to lock/unlock your car or check its status, the app communicates with the vehicle and records your commands and location.
- Telematics Subscription – Many automakers offer telematics services that continuously transmit vehicle data to the manufacturer. This can include detailed trip logs and driving patterns.
- Environmental Sensors – External temperature, rain sensors, and air quality monitors collect data about the environment around the car, which is sometimes shared for weather or traffic reports.
- Key Fob Activity – The key fob communicates with the car, logging when you lock/unlock, start the engine, or approach the vehicle. This can create a timeline of your movements around the car.
- Maintenance and Repair Logs – When a mechanic plugs into your car’s OBD-II port, they can read and sometimes store diagnostic data. This information may be shared with the manufacturer or third-party databases.
Why Automakers Collect Data
Data collection serves several purposes. For the automaker, it helps improve vehicle design, predict maintenance needs, and develop new features. For you, it enables convenience features like real-time traffic updates, remote start, and emergency response. However, the data is also valuable commercially. Anonymized driving data can be sold to insurers, advertisers, or city planners. Some automakers have been criticized for sharing data with law enforcement without a warrant, though practices vary by jurisdiction.
Data Storage and Sharing
Where your data goes depends on the automaker and the services you opt into. Many vehicles have a built-in cellular connection that sends data to the manufacturer’s cloud servers. From there, it may be shared with:
- Insurance companies (with your consent, often for usage-based policies)
- Third-party service providers (e.g., navigation, music streaming)
- Research institutions (for traffic and safety studies)
- Government agencies (under legal request or for safety investigations)
Data is typically stored for a period defined in the privacy policy, which can range from a few months to several years.
How to Protect Your Privacy
You can reduce data collection in several ways, though some features may be disabled as a result:
- Review the privacy settings in your car’s infotainment system. Many vehicles allow you to disable data sharing for diagnostics or telematics.
- Do not connect your smartphone unless necessary. If you do, review which permissions the car requests.
- Use a physical GPS blocker or Faraday pouch for your key fob to prevent unauthorized scanning.
- Check your owner’s manual for a data collection disclosure. In some regions, you have the right to opt out of certain data sharing.
- Use the car’s guest profile for infotainment instead of a personal profile.
- Disable voice assistant features if you are uncomfortable with voice recording.
Common Misconceptions
One common misconception is that your car is constantly recording audio or video. While some vehicles have driver monitoring cameras, they typically only activate when safety features are in use. Similarly, voice assistants are usually triggered by a wake word, not continuous recording. Another misconception is that you can completely turn off data collection by disconnecting the battery. Modern cars have backup power for the telematics unit, and disabling it may violate the terms of your warranty or subscription.
Regulations and Your Rights
Data collection from connected cars is subject to privacy laws in many countries. The General Data Protection Regulation (GDPR) in Europe gives you the right to access, correct, and delete personal data. In the United States, there is no comprehensive federal law, but some states have enacted specific vehicle privacy laws. For example, California’s Consumer Privacy Act (CCPA) provides some protections. However, enforcement is often reactive, and automakers may argue that data is anonymized or necessary for safety.
Future Trends
As vehicles become more autonomous, data collection will increase. Self-driving cars rely on a constant stream of sensor data to navigate. This raises new privacy concerns, such as who owns the data generated by a car when the driver is not actively controlling it. Some automakers are exploring blockchain-based solutions to give drivers more control over their data, but these are still in early stages.
Frequently Asked Questions
Does my car track me even when I’m not driving?
Some vehicles with remote access features can report location and status while parked. This is often used for theft recovery or to check if your car is locked. However, the frequency of updates varies by manufacturer and may be limited by battery-saver modes.
Can I delete the data my car has collected?
You can reset your car’s infotainment system to factory settings, which will clear local data like contacts and navigation history. However, data already transmitted to the manufacturer’s cloud is not easily deleted. You may need to contact the automaker directly to request deletion, and your ability to do so depends on local laws.
Is driving data shared with my insurance company without my knowledge?
Insurance companies generally require your explicit consent to access driving data, typically through a telematics program or a mobile app. However, if you have a built-in telematics system, the automaker may share anonymized data with third parties, which could indirectly affect insurance risk assessments.
How can I see what data my car is collecting?
Many automakers provide a privacy dashboard or a detailed privacy policy on their websites. You can also check the infotainment system’s settings menu for a data sharing or privacy section. If you are unsure, contact the manufacturer’s customer service and ask for a copy of your data.
Will using a GPS jammer stop my car from tracking me?
GPS jammers are illegal in many countries because they can interfere with emergency services and other critical systems. Additionally, they may not block cellular or Bluetooth data transmission. Using one could also void your vehicle warranty or result in fines.
Are electric vehicles more likely to collect data?
Electric vehicles often have more sensors and connectivity features to manage battery and charging. They may also be more dependent on cloud services for route planning to find charging stations. However, the types of data collected are similar to conventional connected cars.
