You take a spontaneous detour on a road trip—perhaps a late-night snack run, a quick errand at a discreet medical clinic, or a stop at a political rally or place of worship. In the old days, that little side trip stayed between you and the open road. Today, your connected car quietly logs the precise GPS coordinates, arrival time, and how long you lingered—then beams it straight to the automaker’s servers. What happens on the road no longer stays private. It ends up in databases sold to insurers, lenders, data brokers, and more.

Modern vehicles function as sophisticated tracking devices. Since the early 2020s, nearly all new cars sold in the U.S. include telematics systems with GPS, accelerometers, and constant connectivity. These systems record not only speed, braking, and acceleration but also exact locations and timestamps. The data reveals deeply personal patterns: where you go, when, and for how long.
