Today’s vehicles have evolved far beyond simple transportation machines. Modern cars equipped with internet connectivity and sensors collect vast amounts of personal data about drivers and passengers, from location tracking and driving habits to biometric information like facial expressions, creating what privacy advocates call a “privacy nightmare on wheels.” Research from the Mozilla Foundation found that cars are the worst product category for privacy they had ever reviewed.
The data collection happens largely in the background as drivers go about their daily routines. Connected cars can transmit information wirelessly to manufacturers, third-party service providers, and other companies in real time. What data gets collected and who has access to it remains unclear to most vehicle owners.
Privacy concerns have intensified as reports emerge about how this information gets used. The Federal Trade Commission has noted that data from connected cars could be used to stalk people or affect insurance rates. Meanwhile, Australia’s privacy laws don’t require the specific disclosures mandated in some U.S. states, leaving drivers with even less visibility into what happens with their personal information.
How Modern Cars Collect and Use Data
Modern vehicles function as sophisticated data collection systems, gathering information through cameras, microphones, sensors, and connected apps. This information flows to automakers, insurance companies, data brokers, and various third parties with minimal transparency about its ultimate use.
Types of Data Collected by Connected Vehicles
Modern connected cars collect an extensive range of personal information that goes far beyond basic vehicle diagnostics. According to the Mozilla Foundation’s research, cars are the worst product category for privacy they’ve ever reviewed.
The data collection includes location tracking, driving behavior patterns, speed, braking habits, and even biometric information. Some manufacturers state they can collect genetic information, with GM’s Cadillac, GMC, Buick, and Chevrolet brands noting in their California Privacy Statement they may gather “genetic, physiological, behavioral, and biological characteristics.” Nissan’s privacy policy goes further, claiming they can collect information about drivers’ “sexual activity” and intelligence, which they infer from personal data.
Cars also capture information through cameras, microphones, and sensors that monitor both the interior and exterior environment. These systems track not just who’s driving but also passengers and even pedestrians outside the vehicle.
Who Has Access to Your Car Data
Automakers share and sell driving data to multiple entities including service providers, data brokers, government agencies, and businesses. The collected information flows to OEMs, Tier-1 suppliers, telematics providers, insurers, mobility platforms, and infrastructure operators.
At least 56% of car brands’ privacy policies state they can voluntarily share personal data with law enforcement or government agencies in response to a simple request, without requiring a warrant. This puts already-overpoliced communities and vulnerable groups like people seeking gender-affirming care, abortion services, or undocumented immigrants at particular risk.
Insurance companies receive direct access through telematics systems that monitor driving behavior. While these systems initially started as optional dongles, they’re rapidly becoming built-in features. Industry reports indicate that most cars sold in 2020 already had telematics built in, with predictions that 91% of vehicles will have embedded telematics by 2026.
Hidden Surveillance Features in Modern Automobiles
Vehicle surveillance capabilities extend beyond obvious sensors to features marketed as convenience or safety tools. VW’s Car-Net offers “boundary alerts” and “curfew alerts” that notify owners when vehicles leave designated areas or operate past set times. While marketed for monitoring young drivers, privacy advocates warn these features enable controlling or abusive behavior.
BMW’s Digital Key allows car sharing via text but also lets the primary user set limits on other drivers’ speed and stereo volume. Tesla, Ford, Lincoln, Mercedes-Benz, Hyundai, Kia, and GM brands allow account holders to track other drivers’ locations whenever they’re behind the wheel.
Outward-facing cameras on vehicles like Teslas record video of people and places outside the car, creating surveillance concerns for pedestrians and bystanders who never consented to being monitored. These cameras can capture footage continuously, storing information about locations, times, and individuals encountered during normal driving.
Privacy Concerns Raised by Vehicle Data Collection
The vast amounts of personal information collected by modern vehicles have sparked significant privacy worries among consumers and advocates. Data sharing practices, weak legal protections, and security vulnerabilities create multiple avenues for potential harm.
Potential Risks of Consumer Data Sharing
Car manufacturers can collect and share data about sexual activity, with Nissan stating in its privacy policy that it may share such information with marketing partners. GM’s various brands indicate they can collect genetic, physiological, and biological characteristics from drivers. Nissan also claims the ability to collect data about a person’s intelligence.
At least 56% of car brands’ privacy policies state they can voluntarily share personal data with law enforcement in response to a simple request, without requiring a warrant. Privacy advocates have raised concerns about how data from connected cars could be used to stalk people or affect their insurance rates.
The surveillance capabilities extend beyond drivers. Tesla and other vehicles equipped with outward-facing cameras can record video of pedestrians and places outside the car, raising concerns about mass surveillance without consent.
Regulatory Gaps and Legal Protections for Drivers
Current privacy laws in the United States offer minimal protection against automotive data collection. Car companies place the burden on consumers to protect their own privacy by opting out of data collection when possible, informing passengers about privacy practices, and ensuring data deletion before selling vehicles.
The European Union provides stronger privacy protections through stricter laws that make it more difficult for law enforcement to access private data from corporations. This contrast highlights how regulation, rather than corporate goodwill, determines privacy protection levels.
News reports have suggested that biometric, telematic, geolocation, and video information collected from cars presents serious privacy risks. The lack of comprehensive federal privacy legislation leaves drivers vulnerable to data misuse.
Impacts of Data Breaches and Leakage
Most car brands studied in recent research failed to meet basic security standards, marking the first time all products in a single category earned security warnings. Sixty-eight percent of car companies experienced a leak, breach, or hack in the past three years.
Toyota exposed data from 2.5 million customers for over a decade due to a misconfigured cloud system. Hyundai used an example encryption key copied from a tutorial, similar to using “12345” as a password. Volkswagen and Honda made mistakes that exposed millions of customer records.
Many data exposures resulted from car companies’ own errors rather than sophisticated hacking. The combination of sensitive data and weak security creates opportunities for criminals to access personal information or potentially gain control of vehicles with basic hacking kits purchased online.
