Why is maintaining a safe following distance important in group riding?

Maintaining a safe following distance in group riding is crucial primarily because it allows for sudden stops. In a group setting, the dynamics can change quickly due to various factors such as road conditions, traffic, or the behavior of other riders. If the rider in front needs to stop suddenly, having a safe following distance gives you the time and space to react appropriately without colliding into them. This distance also helps prevent chain reactions where one rider's sudden stop could lead to subsequent riders being caught off guard, thereby enhancing overall safety within the group.

The other options do not contribute positively to the safety of group riding. While increasing speed may seem like a benefit, it could lead to a higher risk of accidents if the group is not able to stop efficiently. Getting closer to other riders might create a cramped riding space, which is counterproductive to maintaining safe distances and would increase the risk of collision. Lastly, reducing visibility contradicts the principles of safe riding; riders need adequate space to see and react to potential hazards, which is compromised when they do not maintain an appropriate distance.
