Tesla's new Waze-like real-time traffic system as part of its mapping software update could help handle this. If the autopilot system (engaged or in ghost mode) generates an error signal (either binary or some variable degree of error) that is pushed to the traffic system along with the traffic data, it could easily alert other drivers (and hopefully the autopilot system) of such problems. Considering they have enough data to do realtime traffic analysis, they easily should have enough data to determine problem areas for the autopilot.
