Digital instruments are obviously more accurate. Why do most cars choose pointer instruments?

First of all, it should be noted that at present, most dashboards have the function of digital display of vehicle speed, and they exist on the dashboard at the same time as the pointer instrument. As for why there were no digital instruments in the car in the early years, they were all analog instruments, that is, mechanical instruments. First, the mechanical instrument can display the current speed of the car more intuitively and accurately. Secondly, it is limited by the accuracy, real-time, reliability and cost of the previous sensor acquisition. But now this condition is no longer valid.

First of all, even the old driver, sometimes the surrounding environment is too noisy, it is inevitable to glance at the tachometer. At this time, the advantage of the pointer table is unparalleled. Because the pointer table shows specific information, while the number table shows abstract information. People's response to specific information is extremely fast, almost instantaneous, but the response speed to abstract information is a beat slower.

At present, the analog pointer instrument panel is still an advanced vehicle speed representation tool, and the instrument panel is a fixed-size area, so the intuitive display of vehicle speed is more important than absolute accuracy. For example, some skilled old drivers can know the approximate speed only by scanning the approximate position of the pointer with the corner of their eyes, without reading accurately and being too distracted. Then the pointer can intuitively show the changing trend of speed.

It's like a scene in a movie. Something is going to explode, and the air pressure, water pressure and voltage instruments are rushing up in a thrilling way. There must be a red area to remind you of the danger at this time. Therefore, the pointer dashboard makes the driver more confident and generally knows how fast he is driving. Digital instruments only accurately reflect quantity, while pointer instruments reflect both quantity and proportion.
