There is a "Smart Driver" option in the myChevrolet app. If it is enabled, which it is by default, it collects data such as "Hard on the brakes" and "rapid acceleration" dates and times.
If you have used OnStar or the myChevrolet app then it has already been collecting that data and adding it to your credit information.
Check the more info at the bottom right of the screen. When I do that I only see 1.Roadside assistance 2.Explore EV 3. Accessories 4.Parked location and 5.GM Ultium Chargers. There is no reference to Smart Driver nor an option to enroll/delete, but it keeps asking me "Ready to activate your OnStar safety and security services? Drive safer, more connected vehicle today"
I'm assuming that one has to answer "I'm Ready" and then all the data will be collected.
