The Mozilla Foundation recently reviewed 25 major car brands and declared that modern vehicles are “the worst product category we have ever reviewed for privacy.” Not a single automaker met even basic standards for protecting user data. The organization found that cars collect massive amounts of information—from location and driving patterns to biometric data—often without explicit user consent or transparency about where that data ends up.
The Federal Trade Commission (FTC) has already taken notice. The agency recently pursued General Motors (GM) and its subsidiary OnStar for collecting and selling drivers’ precise location and behavioral data without obtaining clear consent. Investigations revealed that data from vehicles could be gathered as frequently as every three seconds, offering an extraordinarily detailed picture of a driver’s habits, destinations, and lifestyle.
That information doesn’t stay within the automaker’s servers. Instead, it’s often shared or sold to data brokers, insurers, and marketing agencies. Driver behavior, acceleration patterns, late-night trips, or frequent stops at specific locations could be used to adjust insurance premiums, evaluate credit risk, or profile consumers in ways few drivers fully understand.
Inside the car, the illusion of comfort and control masks a network of tracking systems. Voice assistants that adjust your seat or temperature remember your commands. Smartphone apps that unlock the vehicle transmit telemetry data back to corporate servers. Even infotainment systems and microphones quietly collect information that could identify you and your routines. The same technology that powers convenience features also enables invasive data collection at an unprecedented scale.
For consumers, awareness is the first defense. Before buying a new vehicle, it’s worth asking the dealer what kind of data the car collects and how it’s used. If they cannot answer directly, it’s a strong indication of a lack of transparency. After purchase, disabling unnecessary connectivity or data-sharing features can help protect privacy. Declining participation in “driver score” programs or telematics-based insurance offerings is another step toward reclaiming control.
As automakers continue to blend luxury with technology, the line between innovation and intrusion grows thinner. Every drive leaves behind a digital footprint that tells a story—where you live, work, shop, and even who rides with you. The true cost of modern convenience isn’t just monetary—it’s the surrender of privacy. The quiet hum of the engine as you pull into your driveway should represent freedom, not another connection to a data-hungry network.
