Anyone here actually reverse engineered their car's systems to strip out the telemetry and tracking modules? Most modern vehicles are running embedded Linux or QNX with cellular modems constantly phoning home. The CAN bus is usually accessible via OBD-II, but newer models encrypt diagnostic protocols and lock down ECU firmware updates. Would love to hear if anyone's successfully disabled the telematics unit without bricking safety systems or triggering limp mode. The challenge is separating legitimate vehicle functions from the surveillance layer without voiding warranties or breaking regulations.
