In late 2015, iPhone and PlayStation 3 hacker George Hotz teased a project that sounded like a dream: his new company would produce a $1,000 consumer product that could grant your car semi-autonomous capabilities. Eleven months and one terse letter from the National Highway Traffic Safety Administration later, Hotz killed the project.

About a month after that, Hotz resurrected it as a two open-source efforts, splitting the hardware and software of the self-driving tech he had created with the rest of his company, Comma.ai. Hotz always talked like he wanted to start a DIY car revolution to take on the car industry (and Elon Musk especially). Open sourcing the plans only increased the chances of it happening.
