While I don't disagree -  I think that concept has already jumped the shark.  As of 2 weeks ago I picked up a new car I am leasing, which came with an App.  The app in question allows me to lock/unlock, and/or start the car, pretty much from anywhere  (it is NOT using direct connections to convey these commands, so I could be hundreds of miles away).  That car isn't running Android, but it might as well be, since the app in question is both on IOS and Android.  Besides that - it also has full access to all on-board diagnostics, etc.

The API is already exposed, so frankly there's no telling what else it has access to.  I'd also love to say that I could turn down that car, but EVERY new car that particular manufacturer has these features, which cannot be "turned off".  I happen to drive a gen 2 hybrid, but my wife's definitely NOT hybrid SUV has the exact same feature set.
