At the circuit, the drivers had already gone halfway into their race with the last five spaced across the first half of the sixth lap.
For the race at the Infinite Eight Circuit, the drivers needed to complete twelve laps around and within the four kilometres tall mountain. Although the mountain was four kilometres or so tall, the length of the circuit wasn't the same.
As the circuit occupied both the inside and outside of the mountain, extending even underground, it had a length of forty two kilometres —which was still child's play for a racing shuttle. The 'short distance' creates the scenario of multiple repetitions, resulting in the race being twelve laps around the circuit.
