If a passenger disputes an extra meter charge caused by a detour around an unexpected police roadblock or sudden road collapse, how should the driver handle the complaint?

1. Insult the passenger for questioning the driver's integrity
2. Explain the unexpected roadblock calmly, show the real-time navigation detour log, and if the passenger remains dissatisfied, offer a reasonable fare adjustment or contact the 12328 transport hotline for mediation
3. Refuse to let the passenger exit the car until they apologize
4. Demand double fare because the detour cost extra fuel
