Tesla doesn't have many fans in the open source crowd. It based its car platforms on open platforms like Linux and BusyBox, but it has gone years without sharing the source code their license (the GPL) requires. The company is finally setting things right, though -- more or less, that is. It has posted the source code for both the material that builds the Autopilot system image as well as the kernels for the Autopilot boards and the NVIDIA Tegra-based infotainment system used in the Model S and Model X. While they don't represent the absolute latest code, Tesla is promising to keep pace with newer releases.
