Automatic vehicles are cars that can change gears without the driver needing to manually shift them. They use a system of sensors and computers to determine when to shift gears, making driving easier, especially in stop-and-go traffic. This technology allows drivers to focus more on the road and less on gear changes. These vehicles often come with features like adaptive cruise control and lane-keeping assist, which enhance safety and convenience. Automatic vehicles are becoming increasingly popular due to their ease of use and the growing availability of electric vehicles that also utilize automatic transmission systems.
