This is a conversion of Comma.ai's Openpilot main ML model, referred to as supercombo, to CoreML.
Openpilot runs on Android and more recently on Linux. The hardware inteface called Panda is compatible with iOS (at least over WiFi). There have been 3rd party attempts to package OpenPilot as a standard Android App that can run on any Android phone. Since Apple's A-series chips seem to be more powerful for ML tasks than the current chips that are powering Android devices running OpenPilot on iOS could open up new posibilities.
This is only the main model conversion. There is a lot of glue code that needs to be ran or ported to iOS.
