In which situation is it helpful to use an adaptive cruise control system (ACC)?

Using an adaptive cruise control system (ACC) is beneficial in situations where maintaining a constant speed and safe following distance is critical, such as on motorways and expressways. These environments typically involve higher speeds and more consistent traffic flow, making ACC particularly useful for enhancing driver comfort and reducing fatigue during long journeys.

On winding roads, however, using ACC is not advisable due to the variable nature of such roads, which require frequent adjustments to speed and greater driver attention. Therefore, it's essential to understand that ACC is designed for situations with predictable traffic patterns, allowing for safer and more efficient driving.
