"Rubberband AI" is a term used to describe a certain type of simple artificial intelligence used primarily in kart and arcade-style racing games. Basically, when your vehicle gets out ahead of the pack, the computer increases the speed of the other vehicles to compensate. When you are behind, the computer will slow the other vehicles down to allow you to catch up. This forces the player to use weapons or nitro boost instead of superior driving skills to beat the computer-controlled racers. Rubberband AI is a source of much frustration (and hair loss) among gamers because it often allows the other racers to go faster than the player, causing the player to lose at the last second.
