Which statement about bicycle riders is correct?

The statement that bicycle riders are likely to be seriously injured in almost any collision with a car is accurate because of the inherent vulnerability of cyclists on the road. When a bicycle is involved in a collision with a vehicle, the cyclist lacks the structural protection that a car provides to its occupants. This disparity in size, weight, and safety features makes cyclists considerably more susceptible to severe injuries, regardless of the circumstances surrounding the collision.

When evaluating the other statements, it's important to note that bicycle riders are required to ride with the flow of traffic, which is a key tenet of safe cycling. This means that choosing to ride against traffic would contradict safe riding practices and established traffic laws. Thus, the statement about riding facing traffic would not hold true.

Overall, understanding the risks faced by cyclists and the importance of following traffic rules is crucial for maintaining safety for both cyclists and motorists.
