The Invisible Data Engine
Modern vehicles, often called 'connected cars', are packed with sensors, microphones, cameras, and an array of software that communicates with the internet. While these features provide convenience and safety, they also generate a staggering amount of data.
This isn't just about your mileage or fuel efficiency. Research shows this data includes everything from your precise GPS location and driving habits—like how fast you accelerate and how hard you brake—to in-car communications. Some manufacturers' privacy policies even allow for the collection of incredibly sensitive information, including biometric data, facial expressions, and in some startling cases, inferences about your characteristics and preferences.
What the Northeastern Study Uncovered
A recent study from researchers at Northeastern University, in partnership with Consumer Reports, put this data sharing under the microscope. The findings were stark: they tested 21 vehicles and found that 19 of them transmitted data to third-party domains, including many known for advertising and tracking. The investigation also looked at the smartphone apps that accompany these cars, which often act as an even wider gateway for data collection. The study found that companion apps for brands like GM, Honda, and Nissan sent personally identifiable information—such as a car owner's name, email address, precise location, and Vehicle Identification Number (VIN)—to outside companies. Unlike a temporary online tracker, a VIN is a permanent identifier for your vehicle, which, when paired with an email or location, makes it easy to build a detailed and permanent profile of a driver's life.
Who Are These 'Third Parties'?
The data from your vehicle doesn't just stay with the car company. It's often shared or sold to a complex web of other businesses. The Northeastern study identified a host of well-known tech giants as recipients of this data, including Google, Meta, Microsoft, and Amazon, among others. Beyond big tech, the information flows to data brokers—companies that specialize in collecting personal information, packaging it into detailed consumer profiles, and selling it. Other third parties include advertising firms looking to serve you targeted ads and, in some cases, insurance companies. Several reports have highlighted instances where driving behaviour data was shared with data brokers who then sold it to insurance firms, potentially affecting drivers' premiums without their direct knowledge.
Why Your Driving Data Is a Goldmine
The market for car data is a booming business, with some analysts projecting its value to reach hundreds of billions of dollars. For advertisers, your location, driving patterns, and in-car media choices are invaluable for creating highly targeted campaigns. If you frequently drive to a certain coffee shop, you might start seeing ads for a competitor. For insurance companies, access to real-time driving data like speed, braking habits, and time of day driven allows for 'usage-based' premium calculations, which could either reward safe drivers or penalize others. Automakers themselves use the data for research and development, but also to create new revenue streams by monetizing the information their vehicles collect every second they are on the road.
Can You Take Back Control?
For consumers, opting out of this data collection is incredibly difficult, and often, impossible. Privacy policies are frequently long, confusing, and vague, making it hard for the average owner to understand what they're agreeing to. In many cases, simply being a passenger in a car is considered consent to its data collection policies. Some manufacturers warn that refusing data sharing agreements will result in 'reduced functionality' or may even disable key features like over-the-air updates and navigation. While some regulations like GDPR in Europe offer protections, the framework around vehicle data remains a complex and evolving landscape. Experts argue that greater transparency and stronger consumer protection laws are urgently needed to give drivers meaningful control over their own information.
