In which situation is it purposeful to use an active lane change assist system?

Active lane change assist systems are designed to help drivers safely change lanes by monitoring the surroundings and guiding the vehicle. Using these systems on motorways and motorway-like roads is purposeful because these roads typically have clearly marked lanes, higher speeds, and more traffic, making lane changes more critical and sometimes challenging. The system can help prevent accidents by alerting the driver to vehicles in blind spots or by assisting with smooth lane changes. On roads without lane markings, the system cannot function properly because it relies on detecting lane boundaries, so it is not effective there. Therefore, these systems are best suited for motorways and similar roads with clear lane markings.
