Final answer:
It is true that high-speed crashes can lead to internal injuries or death as internal organs collide with the body structure due to momentum. Car safety features like crumple zones help reduce the impact force and protect occupants.
Step-by-step explanation:
When people are in a crash at high speeds, they indeed can suffer injuries or die from the internal organs hitting their own body structure. This statement is true. In a high-speed impact, the body's momentum can cause internal organs to collide with the skeleton or other organs, leading to trauma or internal injuries. Such injuries are particularly dangerous because they may not be immediately visible.
Modern car designs incorporate features such as plastic components and crumple zones to extend the time of collision. This results in a lower force exerted on the car's occupants during a crash. By doing so, the risk of severe injury or death is significantly reduced as the energy from the collision is absorbed and dissipated by the car's structure before it affects the human body.
