What is a challenge posed by taller vehicles on the road?

Taller vehicles, such as SUVs and trucks, present a challenge primarily because they can obstruct the visibility of drivers in smaller passenger cars. When a taller vehicle is next to or in front of a smaller car, it can limit the smaller car driver's view of the road, traffic signals, pedestrians, and other important visual information. This decreased visibility can lead to potential safety hazards, including difficulty in judging distances and gaps in traffic for safe maneuvering.

In contrast, increased fuel efficiency, less cargo space, and improved aerodynamics are characteristics that do not typically place taller vehicles at a disadvantage in the context of driving safety and visibility for other road users. Therefore, the challenge of visibility is a significant factor to consider when assessing the impact of larger vehicles on the driving environment.
