I don't see a thread started on the NYT article about GM selling telematics info to LexisNexis which is then being sold to insurance companies. From the article:
Upon Mr. Dahl’s request, LexisNexis sent him a 258-page “consumer disclosure report" ...
What it contained stunned him: more than 130 pages detailing each time he or his wife had driven the Bolt over the previous six months. It included the dates of 640 trips, their start and end times, the distance driven and an accounting of any speeding, hard braking or sharp accelerations. The only thing it didn’t have is where they had driven the car.
On a Thursday morning in June for example, the car had been driven 7.33 miles in 18 minutes; there had been two rapid accelerations and two incidents of hard braking.
According to the report, the trip details had been provided by General Motors — the manufacturer of the Chevy Bolt. LexisNexis analyzed that driving data to create a risk score “for insurers to use as one factor of many to create more personalized insurance coverage,” according to a LexisNexis spokesman, Dean Carney. Eight insurance companies had requested information about Mr. Dahl from LexisNexis over the previous month.
And there's been a long running thread on the Camaro forum: https://www.camaro6.com/forums/showthread.php?t=622276 as well as the Mozilla Foundation report from last September: https://foundation.mozilla.org/en/blog/privacy-nightmare-on-wheels-every-car-brand-reviewed-by-mozilla-including-ford-volkswagen-and-toyota-flunks-privacy-test/
Many of the people affected by this never opted in or agreed to be tracked. Apparently it's not unusual for the dealers to "helpfully" enable these features for their customers. I'm staying with pre-network enabled cars for as long as I can. You'll have to pry my cold dead hands from the steering wheel...
EDIT: Found the thread over in Off Topic. Didn't look there, seems pretty On Topic to me.
