I usually like gas2.org. But this article is terrible. They make it appear as though: Tesla & Elon Sponsored the competition to hack a Model S That Tesla backed out of paying the $10,000 prize That a Model S is vulnerable to hacking Gas 2 | Bridging the gap between green heads and gear heads.
Thanks to MrKevinSD for correcting the mistakes in the comments. That was pretty sloppy reporting. And pretty lame claim of success too, if they didn't do anything not already allowed by the app.
