 This also allows for instant changes in direction - if the driver approaches a wall, the Batpod's central frame will rotate to keep the driver upright (the inspiration for this useful chassis feature may well have been the innovative wheel configuration on a Killough Platform into omnidirectionally mobile chasses).The Batpod's chassis also elongates, allowing the rider to pass under low-hanging obstacles, as when Batman slaloms underneath a tractor trailer the Joker is driving.The term "Batpod" is mentioned by Alfred Pennyworth only once in the movie.
