Navigation systems can be useful for drivers, but they also represent a significant source of distraction. Although these systems provide valuable information, such as directions and routes, they require the driver to divert their attention from the road to interact with them, whether by looking at the screen or adjusting settings.

- **Visual and cognitive distraction**: By looking at the navigation system's screen, the driver may lose sight of the road, increasing the risk of accidents. Additionally, processing the system's information can mentally distract the driver.

- **Comparison with other systems**: Other assistance systems, such as the **lane departure warning** or the **parking assistant**, are designed to alert the driver in a way that does not require diverting attention from the road. For example, the lane departure warning uses lights, sounds, or vibrations to alert the driver without needing to look at a screen.


In summary, although navigation systems are valuable tools, their use can distract the driver, which justifies the statement that they can also be a significant source of distraction.
