“General Motors said Friday that it had stopped sharing details about how people drove its cars with two data brokers that created risk profiles for the insurance industry. The decision followed a New York Times report this month that G.M. had, for years, been sharing data about drivers’ mileage, braking, acceleration and speed with the insurance industry. The drivers were enrolled — some unknowingly, they said — in OnStar Smart Driver, a feature in G.M.’s internet-connected cars that collected data about how the car had been driven and promised feedback and digital badges for good driving. Some drivers said their insurance rates had increased as a result of the captured data, which G.M. shared with two brokers, LexisNexis Risk Solutions and Verisk. The firms then sold the data to insurance companies. Since Wednesday, “OnStar Smart Driver customer data is no longer being shared with LexisNexis or Verisk,” a G.M. spokeswoman, Malorie Lucich, said in an emailed statement. “Customer trust is a priority for us, and we are actively evaluating our privacy processes and policies.”
