What advantage does using cruise control provide?

Using cruise control mainly helps reduce driver fatigue on long-distance drives. When cruise control is engaged, it maintains the vehicle's speed without the driver needing to keep their foot on the accelerator. This allows the driver to relax their right leg and focus more on steering and monitoring the road ahead rather than constantly adjusting speed, which can be physically and mentally tiring during long trips. By creating a more relaxed driving experience, cruise control can help maintain alertness and comfort over extended periods.

While it can contribute to fuel efficiency by maintaining a constant speed, the primary benefit in terms of comfort and long drives is its capacity to decrease fatigue.
