Step-by-step explanation:
The question asks for the number of bicyclists who are killed or injured in the U.S. each year. Unfortunately, the references provided do not give a specific answer to this question, as they focus on motor vehicle injuries, driver death rates, and the demand and supply for bicycles, but do not directly address bicycle injury or fatality statistics. Nevertheless, it is important to emphasize the need for road safety and awareness for all users, including bicyclists. To answer questions such as the one presented, reliable and up-to-date statistics from sources such as the National Highway Traffic Safety Administration (NHTSA) or the Centers for Disease Control and Prevention (CDC) would typically be consulted.
