Privacy in Modern Cars and Trucks: Are Your Secrets Safe on Wheels?

Data Privacy
We live in an era where our lives are intertwined with technology, even while on the move. From voice-activated virtual assistants to cars that can park themselves, innovation has transformed the automotive industry. But, as we embrace these advancements, we must also consider the cost – our privacy. Recent findings by the Mozilla Foundation have shed light on the alarming state of privacy in modern vehicles, revealing that cars rank as “the official worst category of products for privacy that we have ever reviewed.”

The Privacy Predicament

As cars evolve into high-tech machines, they are becoming data-rich environments. The convenience of having your car recognize when you’re drowsy and suggest nearby coffee shops is undeniable. However, what many of us fail to realize is that while our vehicles are making our lives more comfortable, they are also gathering an astonishing amount of personal data.

According to the Mozilla Foundation’s study, every automotive brand examined collected more personal data than necessary and used it for purposes beyond vehicle operation. This unsettling fact places cars in the same league as mental health apps, with 63% of them also receiving privacy-related criticism. Our vehicles, it seems, are learning more about us than we may be comfortable with.

What Data Is Being Collected?

Connected cars have the capacity to collect a wealth of information, including medical history, genetic data, driving habits, music preferences, and even intimate details about our personal lives. From this, automakers can deduce more about us than we might like to admit, including our intelligence, abilities, and interests. The implications of this data collection are far-reaching, and it raises important questions about who has access to this information.

Privacy Breaches and Government Access

Perhaps the most alarming revelation is that the majority of car brands studied not only collect our data but also share and even sell it. A staggering 76% of these automakers allow the sale of personal data, and 56% permit sharing with government or law enforcement agencies upon request. This is a clear violation of our privacy and poses significant risks.

Europe’s Influence on Data Protection

Interestingly, two automakers, Renault and Dacia, stood out for their commitment to data protection. Both asserted that all drivers have the right to have their personal data deleted, a stance that aligns with Europe’s robust General Data Protection Regulation. However, researchers couldn’t confirm whether any of the 25 brands encrypted all the personal information stored in their vehicles, a basic requirement for earning Mozilla’s Minimum Security Standards designation.

Creepiness Rankings

To put the data privacy issue into perspective, Mozilla ranked the automakers from creepiest to least creepy. Nissan, Chevrolet, and Kia topped the list of “super creepy” brands in terms of data collection, while Jeep, BMW, Cadillac, and Tesla were slightly less sinister. Dacia, known for its budget-friendly cars, was the sole “very creepy” automaker, likely due to its limited suite of connected services.


Our cars are evolving into more than just modes of transportation; they are becoming data-hungry machines, eager to learn every detail about our lives. While technology can undoubtedly enhance our driving experience, it’s vital to address the alarming privacy concerns outlined in Mozilla’s report. The fact that cars are now considered the “official worst category of products for privacy” should give us all pause for thought.

As consumers, we must advocate for stricter data privacy regulations within the automotive industry and demand transparency from automakers. Only by taking collective action can we hope to protect our privacy while enjoying the conveniences of modern vehicles. After all, in the age of smart cars, we should be in control of the data we share, not the other way around.
