In a recent New York Times article, Kashmir Hill reported how everyday moments in your car like these create a data footprint of your driving habits and routine that is, in some cases, being sold to insurance companies. Collection often happens through so-called “safe driving” programs pre-installed in your vehicle through an internet-connected service on your car or a connected car app. Real-time location tracking often starts when you download an app on your phone or tap “agree” on the dash screen before you drive your car away from the dealership lot.
