While riding a saddled pig, you can use the carrot on a stick to accelerate the pig. At about 75% speed, you can switch to another item in your hotbar and the pig will continue to follow orders as if you were holding a C.O.A.S. until it slows down to about 25%, where it will begin to move in slightly different directions. soon after it will stop, and the carrot will be needed to start the pig again.

Not sure if intended or just a bug.

Applies to both creative and survival.
