How we turned a real car into a Mario Kart controller by intercepting CAN data

The report describes a hands-on demo converting a Renault Clio into a game controller by tapping the CAN bus with inexpensive splicers and a Kvaser USBCAN interface, identifying steering/brake/throttle arbitration IDs, and translating them into SuperTuxKart inputs via Python (python-can, pynput). It details building a state-machine architecture to throttle input rates, selecting thresholds for controls, displaying key CAN frames, and resolving instability caused by thread-unsafe bus access by switching to can.ThreadSafeBus. The piece shares practical constraints (power, battery, steering effort) and notes future plans to replicate the concept with a more portable platform.
