This is due to the number of cameras, weight sensors and smartphone connected devices that transmit troves of personal data to unknown entities. In one instance, a woman going through divorce proceedings was reportedly tracked by her husband using the "Mercedes Me" app, which he could not be barred from accessing by Mercedes because he originally obtained the car loan and title.
