The game has a secret CPU ghost mode which can be accessed under the Time Trial menu by pressing Start on a controller in port 2 while selecting a driver. This triggers a CPU cursor to appear, allowing the player to select a ghost driver to compete against. However, the CPU ghosts are capable of interacting with elements of a track's mechanics, like the ice blocks found in Vanilla Dome.

If the player allows the CPU to destroy these blocks, then drives over where the blocks were, then saves and race against their own ghost, a glitch will occur where the ghost will vanish when it touches the block that was supposed to have been destroyed and trigger a visual error where the player's tires will cycle between two frames of animation even while in an idle position. This glitch only occurs when the player and the ghost use the same driver.
