Overview
The exact location of this challenge is in the east end of North Pyongyang, in the parking area. To start the challenge the player must first enter the Metro Bus with a "$" above it so that he/she will be prompted with the message that tells him/her the outlay of the mission.

Once the challenge is started, the yellow, total 4:00 counter will start ticking and the customers will spawn. To pick up a customer, the player has to stop the bus next to them and honk. Each customer has their desired drop off location printed above their heads. Once the customer has entered the bus, their desired location is shown on the minimap, as well as a new, customer timer. This timer increases every 6 seconds based on the average speed of the bus during the period. The timer does not increase if the speed is under 70 kph. Once the customer is dropped off the remaining customer timer is added to the total timer. The best way to complete this challenge is to ignore customers which have short trips, such as remaining in the same location or North Pyongyang-East Pyongyang, as this will make player unable to increase customer timers significantly, effectively wasting 40 seconds of total timer. It is much better to waste 20 seconds of total timer to find a customer with a long route.

Upon completing the challenge, the player will be rewarded with a sum of $25,000. The player can keep the metro bus. The number of completed fares will be added in the "challenges" page in the player's PDA under "status", and it will become the base for the new fare goal the next time the challenge is accepted.
