Your car is selling your data

Why This Matters

Connected cars have quietly become one of the most invasive data-collection platforms in consumers' lives, with GM's FTC settlement showing that driving behavior data was sold to brokers and used to shape insurance rates — often without drivers' meaningful knowledge or consent. Mozilla's research suggests this isn't one bad actor but an industry-wide norm, raising the stakes for privacy regulation as vehicles grow more software-defined.

How it started

Earlier this year, the Federal Trade Commission issued an unprecedented penalty against General Motors: a five-year ban on selling customer data to consumer reporting agencies and third-party data brokers.

For years, GM had been collecting all sorts of data on its customers — such as how often they sped or whether they drove at night — and selling it to brokers to generate risk profiles for insurance companies. More often than not, drivers were unaware of the degree to which their data was being collected. Many had unknowingly consented to it by signing up for an OnStar connected services plan, which activated a feature called Smart Driver that collected their driving data.

GM was then turning around and sharing that data with two data brokers, LexisNexis and Verisk, both of which work with the insurance industry. In a 2024 blockbuster investigative report by The New York Times, some drivers said their insurance rates went up as a result of the data collection. The enrollment process was so confusing that many vehicle owners had no idea their data was being shared. Under the settlement with the FTC, GM has to make it easier for drivers to turn off location tracking, as well as enable them to access and delete their data collected by the automaker.

But GM isn’t the only automaker vacuuming up data on its customers. A team of researchers from the Mozilla Foundation spent months examining the privacy policies of all the major car companies for a report they were working on in 2023. Their conclusion: Every single one had “horrible privacy and security,” said Jen Caltrider, who helped author the study. Not only that, but customers were forced to accept overlapping policies for the car, the connected services, the smartphone app, and the financial services through which they received their loan — all of which included data collection provisions.

“And so it was really overwhelming trying to understand what was going on,” Caltrider said.

There has been plenty of corroborating evidence for this. Consumer Reports published its own investigation last year that concluded “nearly every automaker that sells cars in the U.S. is similarly collecting and sharing so-called ‘driver behavior data’ with other companies and continues to do so.”

Cars are particularly problematic compared to phones because the privacy controls are less intuitive. A smartphone owner can generally find and tweak their privacy settings. With a vehicle, the data collection is spread across multiple systems and policies, making it much harder for consumers to understand what is happening. It feels like a free-for-all because automakers are collecting enormous amounts of information without much public scrutiny.
