Domino's is taking a page out of Santa's book on efficient winter transportation. The global pizza chain, which has already invested in high-tech delivery methods like autonomous robots, drones, "zero-click" ordering apps and satellite tracking to deliver food, is now training reindeer to transport pies. Reindeer delivery may be part of a contingency plan for Domino's Japan ahead of what is expected to be a particularly cold and snowy winter, RocketNews24 reports. The chain is attempting a trial period for performing training exercises in the city of Ishikari-- a particularly ice-prone area in Hokkaido-- to figure out if its reindeer delivery initiative is feasible. The technique will involve insulated pizza containers strapped to the animals' backs.
