May an online ride-hailing driver refuse to accept an order or unilaterally cancel an accepted order simply because the trip distance is too short (挑单/拒载)?

1. Yes, drivers have an absolute constitutional right to refuse any order below 10 kilometers
2. No, once an order is accepted via dispatch, unjustified refusal or unilateral cancellation constitutes illegal refusal of service (拒载/挑单) and is penalized
3. Yes, short trips can be cancelled if the driver claims their car needs washing
4. Yes, provided the driver sends an apology emoticon to the passenger
