Trivia

 * The name of this achievement is most likely a reference to an episode in the A Different Way to Campaign series on Halo Waypoint named "The Pedestrian" hosted by Jeremy Patenaude. A Pedestrian, explained by Patenaude, is a player who walks during a part of the campaign level that needs the player to commandeer a vehicle, which fits the requirements of the achievement.
 * The method that is required to unlock this achievement is similar to that of the "They've Always Been Faster" achievement in Halo: Reach.
