What is the standard closing etiquette when an online ride-hailing passenger reaches their destination and prepares to disembark?

1. Accelerate away while the passenger has one foot still on the ground
2. Stop safely at a permitted curb, remind the passenger to check for personal belongings ('Please check your personal belongings / 请带好随身物品'), check the right rearview mirror before doors open, and say goodbye politely ('Thank you, goodbye / 谢谢，再见')
3. Shout at the passenger to hurry up and leave immediately
4. Demand that the passenger surrender their coat as a farewell gift
