comma.ai

comma.ai is an open-source driver assistance system that turns compatible vehicles into semi-autonomous cars through a plug-in device called the comma three. Its openpilot software uses neural networks trained on millions of miles of human driving data to provide adaptive cruise control and lane keeping capabilities comparable to OEM systems at a fraction of the cost. comma.ai's open-source model enables a community of developers to contribute improvements and extend support to new vehicle models, making advanced driver assistance accessible to vehicles that manufacturers chose not to equip with these features.
