wow, thats kind of scary. Though I can see it being beneficial if you have a teen/young adult driving. Kind of a tattle tale report. Although I'm sure it would be more important for insurance companies to have access to data like that, it's still frightening how much data they can gather. Is there anything in any of the agreements you may have signed or said yes to that had this level of data collection listed in the fine print? Although like many, I'm not fond of having data collected about my driving habits (seriously LATE NIGHT DRIVING?!?!) or anything in general, I also don't have anything to hide and have more or less accepted that in a digital age where even your cell phone tracks your every move, even what apps were run and for how long and reports back to google/apple as being the norm. I do however have to point out that we know these devices/services are available and clearly operational. Even with your request to deactivate the service, I'm sure it's still likely that the data is still collected and stored since its almost certainly programmed in the code to collect and report. The big question however is, what does OnStar/GM do with the data for those who un-enroll?
