Why do you think China's heavy trucks are flatheads?

First of all, the line of sight of a flat-top truck is better than that of a long-top truck, with a clearer field of vision, while there is a dead angle in the line of sight of a long-top truck; the direction of a flat-top truck is more accurate, with a smaller turning angle, especially in the space of a narrow terrain, it is easier for a flat-top truck to turn around and make a U-turn; the bodywork of a flat-top truck is in the front, and it is easier to arrange the chassis parts, such as the fuel tank, the air tank, the battery, and the rear tailpipe gas treatment system, etc.; the cab of a flat-top truck can be turned forward as a whole. The cab of flat-top truck can be turned forward as a whole, which is more conducive to the daily inspection and maintenance work, and the maintenance of the engine is more convenient; the driving experience of flat-top truck is better than that of long-top truck, which reduces the fatigue intensity of the driver and the driver and the passenger; and then, the formulation of the national regulations strictly limits the length of the whole vehicle, which results in the weak capacity of the long-top truck. Of course, the safety of the long head of the car is much better than the flat head of the car, more life-saving, traveling in the process of wind resistance coefficient is also more small.
