What do you think the waistline of a car is for?

We are used to the waist line as the boundary, and it is most appropriate to control the height ratio of the upper and lower car bodies in the golden ratio. If the waistline is too high or there is no waistline at all because it is too round, it is easy to appear stiff sideways. Not only is the window the wrong size, but it also appears that people put shirts into their pants, and the belts are particularly high. I don't like the design of high waistline, but experts with local flavor can always disdainfully say that this is the trend. Just as I don't quite understand the difference between Chanel's flip-flops and the flip-flops that can be seen everywhere in the alley, I don't understand why this aesthetic design is respected.
