What is the primary purpose of the 2025 QX55's ProPILOT Assist feature?

The primary purpose of the 2025 QX55's ProPILOT Assist feature is to ease the driver's workload in heavy highway traffic. This advanced driver-assistance system is designed to enhance convenience and safety by providing capabilities such as adaptive cruise control and lane-keeping assistance. By maintaining a safe distance from the vehicle ahead and helping the car stay centered in its lane, ProPILOT Assist significantly reduces the driver's need to constantly adjust speed and steering in stop-and-go situations.

Given the context, options related to monitoring tire pressure, reducing fuel consumption, and managing vehicle maintenance notifications do not align with the primary function of ProPILOT Assist. They address different aspects of vehicle operation or maintenance but do not provide the driver support that the ProPILOT Assist feature is specifically designed for, particularly in the context of driving in heavy traffic scenarios.
