Automatic cars are vehicles equipped with an automatic transmission system, which allows the driver to change gears without manually shifting. This system uses a complex arrangement of gears and hydraulic systems to automatically adjust the vehicle's speed and power, making driving easier, especially in stop-and-go traffic. Unlike manual cars, where the driver must use a clutch pedal and gear stick, automatic cars only require the driver to operate the accelerator and brake pedals. This feature makes them popular among new drivers and those who prefer a more relaxed driving experience, enhancing overall convenience and comfort on the road.
