Pedestrian detection and braking: Sensors that detect and recognize people on foot in the car's path. Some also recognize cyclists and large animals. No detection for dogs or cats yet.
Lane departure alert and assistance: Alerts if the car is about to cross the lane marker without indicating a lane change. Some systems try to steer the vehicle back into its lane (assistance). Others just tell the driver (alert).
Lane centering: Similar to lane departure assist, but centering more subtly keeps the vehicle in the middle of its lane, reducing the effort and attention required from the driver.
Adaptive cruise control: Braking and throttle control to keep the car at a set speed and distance behind other vehicles. The following distance can be adjusted for traffic conditions and driver preference.
