Final answer:
Following too closely to a vehicle in front increases the risk of collision, particularly for motorcyclists. Car safety features like crumple zones increase the time of impact in an accident, reducing injuries to passengers.
Step-by-step explanation:
Understanding Safety Measures in Vehicle Design
Following too closely to the vehicle in front of you is generally a dangerous driving behavior. It can lead to accidents, especially for motorcyclists who have less protection than car occupants. The correct answer to the student's first multiple-choice question is c: It is a factor in collisions caused by motorcyclists.
Car safety features such as crumple zones, the designed to protect passengers during an accident. The purpose of crumple zones is to reduce injury to the passengers by increasing the time of impact during a collision. This allows for a controlled deceleration of the vehicle and reduces the force experienced by the occupants. Hence, the correct answer is a: It reduces injury to the passengers by increasing the time of impact.
