What is a key benefit of the QX55's active safety features?

The key benefit of the QX55's active safety features is their ability to assist in accident prevention. These features are designed to help the driver avoid potential collisions by using advanced technologies such as adaptive cruise control, lane departure warning, blind-spot monitoring, and automatic emergency braking. By actively monitoring the vehicle's surroundings and providing alerts or taking corrective actions, these safety systems significantly reduce the likelihood of accidents, enhancing overall road safety for both the driver and other road users.

Other options do not relate to the primary function of active safety features. For instance, advanced navigation capabilities and aesthetic appeal are not directly influenced by these features, while improvements in fuel efficiency relate more to engine performance and aerodynamics rather than safety systems.
