If a taxi driver finds a passenger's forgotten laptop and the passenger contacts the driver requesting immediate special delivery to an address 15 kilometers away, what is the legal rule regarding return delivery costs?

1. The driver must deliver it 15 km away completely for free and pay for all highway tolls out of pocket
2. The passenger should reasonably compensate the driver for direct operational costs (e.g., standard meter fare or fuel expenses incurred for the special delivery trip), but the driver cannot demand an extortionate ransom reward
3. The driver may demand a cash ransom of 50% of the laptop's retail market value before returning it
4. The driver has the legal right to sell the laptop at a pawnshop if delivery is inconvenient
