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

Adaptive cruise control (ACC) is especially useful on motorways and expressways because these roads have long stretches without frequent stops or sharp bends, enabling the ACC to maintain a set speed and automatically adjust to the speed of vehicles ahead. This increases comfort and safety during long drives. However, on winding roads, ACC is less helpful because curves and frequent changes in speed and direction require the driver’s direct control rather than automated speed management. So, choosing motorways and expressways is correct for when ACC is helpful.
