What emotion could negatively affect a rider's ability to operate a moped safely?

Anger or frustration can significantly impair a rider's ability to operate a moped safely due to the impact these emotions have on decision-making, judgment, and reaction times. When someone is angry, they may become aggressive and take unnecessary risks, such as speeding or weaving in and out of traffic. This heightened state of agitation can lead to poor assessments of situations, making it difficult to react appropriately to hazards. Additionally, frustration can lead to impatience, resulting in abrupt maneuvers that could endanger the rider as well as others on the road. Hence, it's crucial for riders to manage their emotions and maintain a calm demeanor to ensure their safety and the safety of those around them while riding.
