What is the purpose of crushable bumpers in vehicles?

Crushable bumpers are specifically designed to absorb impact energy during collisions, thereby enhancing the safety of both the vehicle and its occupants. When a vehicle is struck, these bumpers flex and deform, which helps to dissipate the energy from the impact instead of allowing it to transfer directly to the frame or cabin of the vehicle. This absorption mechanism reduces the likelihood of severe injury to passengers, as it helps to manage the forces experienced during a crash.

The other options do not align with the main function of crushable bumpers. While enhancing aesthetics, improving fuel efficiency, or providing storage space may be benefits of other vehicle components or features, they do not capture the critical safety role that crushable bumpers play in collision scenarios.
