Why does the dashboard display gear positions when driving an automatic transmission car?

Normally, it doesn't display. Only when a semi-automatic transmission car is shifted into manual mode will it show. Automatic transmission letters: P stands for Park, must be engaged after parking; R, Reverse; N, Neutral; D, Drive. These are the basics. For semi-automatic transmissions, some allow up and down shifting, while others have left and right shifting on the gear lever. Some cars have an O/D switch, which can be turned on during driving to force downshifting, aiding in overtaking. Some cars also have a SPORT switch for switching between sport mode and normal mode. Semi-automatic transmission: Essentially, it's still an automatic transmission but with an added manual mode that electronically switches between different gears to enhance driving pleasure.
When I first started driving, I also wondered why automatic transmissions display gear positions. Later, I realized how useful it is. Although automatic transmissions don't require manual shifting, the gearbox itself constantly switches between gears 1-6. The dashboard showing 'D' tells us we're in automatic mode. If switched to sport mode or manual mode, it displays the specific gear number. Once when driving downhill on a mountain road, I switched to manual mode in 2nd gear, avoiding constant brake use – seeing the gear display gave me great peace of mind. Also, displaying 'R' when reversing is crucial to prevent misoperation. This design is both thoughtful and safe!
As someone who frequently drives long distances, I particularly value the gear position display on the instrument panel. Although automatic transmissions are called 'automatic,' when encountering uphill climbs or overtaking, it's necessary to shift to lower gears to enhance power. The gear display allows me to confirm whether the current mode is correct, such as seeing D4 to know it's in a high gear. Additionally, modern cars come with paddle shifters, and the gear display is essential for coordinating manual operations. More importantly, it prevents accidental touches; if the gear lever is inadvertently bumped, the display allows for immediate correction. After all, driving safety comes first, making this display highly necessary.
