Final answer:
Rear end collisions occur frequently on highways due to drivers following too closely and being unable to react promptly, leading to potentially expensive car damage.
Step-by-step explanation:
Rear end collisions are common on highways because many drivers follow too closely, becoming unable to react in time if the car in front suddenly slows down or stops. This situation is further exacerbated when drivers are distracted or fail to pay attention to the flow of traffic. The principle of Collision Theory helps us understand that more collisions occur when drivers are in close proximity and when there is insufficient time or distance to respond to traffic changes. Such incidents often result in car damage, which can be particularly costly if the driver at fault lacks car insurance. While at lower speeds, as often found in parallel parking scenarios, cars may not sustain significant damage; at higher speeds, such as on highways, the damage can be much more severe and require extensive repairs.
