A lot of backstory here as at one point Musk wanted Hotz to work for Tesla on autopilot, he created a system on his own "on par with tesla autopilot at first launch" then shut down by the NHTSA (or at least in part)... but today he open sourced the software he made. Will be very interesting to see what happens here. I'm sure Tesla, as well as many others will be looking over this code in the days and months to follow.
