Your car spies on you more than your phone, according to Mozilla

Published on April 26, 2026 | Translated from Spanish

A September 2023 report from the Mozilla Foundation reveals that modern cars are a privacy disaster. All 25 brands evaluated failed in data protection. With GPS, microphones, and cameras, they collect location, routes, driving behavior, and even conversations. 84% share or sell your information, and 92% leave you with no control over it.

How data collection works in your vehicle 🚗

Infotainment systems and integrated voice assistants are the main culprits. The car records accelerations, braking, and speed using internal sensors. It also syncs your phone to extract contacts and calls. All of this is stored in the manufacturer's cloud, which can share the data with insurers or advertisers. The user has few options to disable these features without losing basic services.

The smart car that knows you better than your partner 😱

Now it turns out your car knows more about you than your therapist. It knows where you go, when you brake hard, and even who you talk to. The worst part is you can't even blame the neighbor. Next time you complain about traffic, remember that your own vehicle might be selling that information to the highest bidder. And on top of that, you pay for gas.
