when a frontal threat is detected. Wrong-way driving warning issue alerts to drivers when it is detected that they are on the wrong side of the road. Vehicles with this system enacted can use sensors and cameras to identify the direction of oncoming traffic flow. In conjunction with lane detection services, this system can also notify drivers when they partially merge into the wrong side of the road Crash mitigation Pedestrian protection systems are designed to minimize the number of crashes or injuries that occur between a vehicle and a pedestrian. This system uses cameras and sensors to determine when the front of a vehicle strikes a pedestrian. When the collision occurs, the vehicle's bonnet lifts to provide a cushion between the vehicle's hard engine components and the pedestrian. This helps minimize the possibility of a severe head injury when the pedestrian's head comes into contact with the vehicle. Driving task assistance Adaptive cruise control (ACC) can maintain a chosen velocity and distance between a vehicle and the vehicle ahead. ACC can automatically brake or accelerate with concern to the distance between the vehicle and the vehicle ahead. ACC systems with stop and go features can come to a complete stop and accelerate back to the specified speed. This system still requires an alert driver to take in their surroundings, as it only controls speed and the distance between you and the car in front of you. Anti-lock braking system (ABS) restore traction to a car's tires by regulating the brake pressure when the vehicle begins to skid. Alongside helping drivers in emergencies, such as when their car starts to skid on ice, ABS systems can also assist drivers who may lose control of their vehicle. With the growing popularity in the 1990s, ABS systems have become standard in vehicles. Automatic parking fully takes over control of parking functions, including steering, braking, and acceleration, to assist drivers in parking. Depending on the relative cars and obstacles, the vehicle positions itself safely into the available parking spot. Currently, the driver must still be aware of the vehicle's surroundings and be willing to take control of it if necessary. Collision avoidance system (pre-crash system) uses small radar detectors, typically placed near the front of the car, to determine the car's vicinity to nearby obstacles and notify the driver of potential car crash situations. These systems can account for any sudden changes to
