Autopilot is a technology that allows vehicles, such as airplanes and cars, to operate with minimal human intervention. It uses sensors, computers, and algorithms to control the vehicle's speed, direction, and altitude, making it easier for pilots or drivers to manage long journeys. In aviation, autopilot systems can handle tasks like maintaining altitude and navigating routes, which helps reduce pilot workload. In cars, autopilot features can assist with steering, braking, and acceleration, contributing to safer and more efficient driving experiences.
