What is fcw in a car?

FCW stands for Forward Collision Warning. It is a safety feature in modern cars that alerts the driver if there is a risk of a forward collision. FCW typically uses sensors, cameras, and radar to detect the distance and speed of the car in front and the driver's vehicle. If the system detects an impending collision, it will warn the driver with an audio, visual, or vibration alert, allowing them to take corrective action. FCW has been shown to reduce the number of accidents and injuries caused by rear-end collisions.
