Onstar has a feature called Smart Driver that tracks all this. Normally, you would have to agree to sign up for it, but sometimes I think you can automatically be signed up. Of the many GM cars I've owned with Onstar, my 2017 ZL1 was the only one that had this enabled, and I don't recall asking for it. IIRC, you have to call them to get it removed. I never saw it affect my insurance though, so doubt it is automatically reported. My insurance did increase about 17% across my 3 vehicles for latest policy, but that is more to do with inflation and used car prices, according to my agent.
But 2 hard accel and brake events, lol. I wish I still had access to mine. Once, over one trip of 87 miles, it showed 147 hard accels, and 83 hard brakes, but that could've been the day we went to Watkins Glen
