Passively sniffing the CAN bus for sign recognition events would be
entirely undetected - but that would require reverse engineering the
protocol and writing specific code... One might argue that rigging a
dashcam and processing its output on a desktop with some road sign
recognition software (generic pattern recognition neural net trained
with road signs ?) would be less effort - albeit an inelegant effort
duplication.
