George "Geohot" Hotz's semi-autonomous driving add-on,Comma One, didn't work out as planned . However, that doesn't mean the underlying technology will never see the light of day -- far from it. The Comma.ai team has published the source code for both its Openpilot self-driving tech and its NEO robotics platform. You'll need hardware to use this for its originally intended purpose, but anyone who has a grasp of the programming languages involved can use the code for whatever projects they like. While you probably won't see homebrew self-driving cars emerge from this (the law would have something to say about it), don't be surprised if some of the tech finds its way into commercial projects.
