What does the D in an automatic transmission car stand for?

[McAva]

In an automatic transmission car, the D stands for Drive, which allows the car to automatically shift to a comfortable operating state based on road conditions and vehicle speed. Here is an introduction to automatic transmission cars: 1. An automatic transmission, as the name suggests, does not require the driver to manually shift gears. The vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. Generally, there are six gear positions in an automatic transmission car, from top to bottom: P, R, N, D, S, L. 2. The automatic transmission in a car is controlled by an automatic gearbox, which uses planetary gear mechanisms to shift gears. It can automatically shift gears based on the degree of the accelerator pedal and changes in vehicle speed. The driver only needs to operate the accelerator pedal to control the speed.
