Why can a manual transmission car move in first gear without pressing the accelerator?

[VanHolden]

It depends on the minimum throttle setting from the factory (the fuel supply amount when idling at startup), which varies from model to model. If the factory-set minimum throttle value is slightly higher, the car can indeed move in first gear without pressing the accelerator. Some cars can even move in third gear without stepping on the accelerator. Introduction to manual transmission cars: Cars that use a manual shift mechanical transmission (also known as manual transmission, MT) to adjust speed. This means the driver must manually shift the gear lever to change the gear meshing position inside the transmission, altering the gear ratio to achieve speed variation. The gear lever can only be moved when the clutch is depressed. Function of manual transmission cars: Drivers can save fuel by selecting the appropriate gear. The commonly mentioned fuel efficiency of mechanical transmission cars is due to their higher transmission efficiency, which reduces power loss. Driving a manual transmission car requires higher skill levels, and proper and timely gear selection is essential for true fuel savings.
