Adaptive cruise control helps maintain a safe following distance between vehicles by automatically adjusting the speed of the vehicle. Lane-keeping assist alerts drivers when they unintentionally drift out of their lane, reducing the risk of collisions due to lane departure. Automatic emergency braking detects potential collisions and applies the brakes if the driver does not respond quickly enough, helping to prevent accidents or reduce their severity. Overall, these safety features enhance road safety by assisting drivers in avoiding common types of accidents and reducing the likelihood of crashes.
