In a recent exposé by The New York Times, it’s revealed that car manufacturers like General Motors Co., Honda Motor Co. Ltd., and Kia Corp. have been selling detailed driving behavior data to third-party brokers, potentially influencing owners’ insurance premiums.

This practice involves compiling behavioral profiles of drivers based on data from connected cars, including braking habits, speeding tendencies, and aggressive acceleration.

The report features Kenn Dahl, a 65-year-old American, shocked to discover a 21% increase in his insurance premium, attributed to data collected by LexisNexis.

While consumers can access their LexisNexis report, the revelation underscores the importance of scrutinizing connected car settings and seeking privacy protections from manufacturers.
