This doesn't really solve anything. It can equally easily be recording exactly all of that data into some encrypted format on the SD card, which then gets uploaded to the manufacturer when opened with the proprietary application necessary to view the data. The only difference is the choice over exactly when the data is uploaded, which in the US with its insurance system, results in no choice at all.
