They sell your location data, driving habits, etc. then the insurance company buys it and raises your rates. I declined it when I bought my Subaru and they registered my car to someone else's email address, giving someone else access to those features. That module is now on a shelf in my garage. I park in gear (manual) so remote start can launch my car into a wall.
