In a broad-reaching report by 60 Minutes about DARPA and the Internet of Things, the Department of Defense has shown that it can hack General Motors' OnStar system to remote control a last-gen Chevrolet Impala.
The idea that every site, every service, every bit of data that flows through the wondrous tubes of the Internet should be treated fairly is what Net Neutrality is all about. And GM isn't quite on board, at least for mobile data.
GM and OnStar are going to show off an app for Android Wear that lets you lock and unlock the doors and start or stop the engine. It's similar to the one on the Galaxy Gear 2 (demo'd above), but people might actually use it.
