At 50cc, the AI racers do not drift much and rarely perform Mini-Turbos. Most will spin out on the starting line, and they otherwise do not drive or use items efficiently. As the engine class increases, however, the AI will start to become more aggressive, drifting along the inside of turns, holding items behind them to block the player's attacks, performing Rocket Starts more often, and generally driving better and generally becoming more difficult to overcome.
