To ensure **safe driving**, it is important that the navigator is placed at an **appropriate height**. This allows the driver not to have to take their eyes off the road, thus maintaining attention on driving and reducing the risk of accidents.

- **Visibility and attention**: Just like mirrors, which must be well-positioned to offer good visibility without needing to divert the gaze too much, the navigator must be at a height that allows the driver to consult it without losing sight of the road. This is crucial for maintaining attention on the surroundings and reacting in time to any situation.

- **Driver's position**: The driver's position is fundamental for safe driving. The seat must be adjusted so that the driver can see over the steering wheel and not through it. Similarly, the navigator must be in a place that does not require uncomfortable movements or unnecessary distractions.

Placing the navigator at an incorrect height could force the driver to divert their eyes from the road, increasing the risk of accidents. Therefore, it is essential that the navigator is at a height that allows for quick and safe consultation.
