New vehicles aren't just cars and trucks with computers inside, they're computers that just happen to have engines, tires and wind shields. At the very least, stop plugging your device into your vehicle! Newer models can generate around 25 gigabytes of data per hour, pulling from over a hundred different sensors and data points like GPS, diagnostics, cameras, and driver assistance systems. You wanna add to that by giving them direct access to your phone and granting permission? I know it's convenient, but damn! They track your location, driving style, speed, braking, and sometimes even what's happening inside the cabin through mics and cameras. That data often gets shared with insurers, data brokers, or even law enforcement. If you plug directly into your phone, you also give the automaker where you've been when you're not in one of their spy vehicles. All that data is being collected or stored to some degree. Even heart rate and biometrics that comes from steering wheel sensors or driver monitoring cameras are in operation in newer vehicles. The claim is that it's for "safety and fatigue detection." But you know better.
