Re: Protocol could easily have been designed without the Google backend roundtrip
Assuming you don't stick a Progressive tattle-tale device into your car, the black box info doesn't leave the car. You own the car and the black box and there are a limited number of things as the owner of the car that you can do. Regardless no database of private information is being maintained and used for marketing purposes.
You can buy a non-Android phone. Licensing this protocol means every phone (smart home device, any Bluetooth pairing event) uses the Google lookup service and Google gets the data.
