The reason is very simple, if the same car, driving at the same low speed (note, low speed, high speed can not), the front then hit a pedestrian. Imagine if you were the one who was hit, would you expect the bumper to be metal or plastic? Since the bumper is mostly made of a material with good elasticity, it has good impact resistance. This means that it is easy to solve with small bumps, and even if it is off paint, it is not difficult to paint. This is a coup for "a cheap two to make" - car dealers, everyone Save time and money. The front and rear bumpers of the car are so, some body exterior parts, such as fenders, may also be made of lightweight materials such as plastic. Of course, some top sports cars will also use a large amount of carbon fiber material instead of metal materials on the outer body. The purpose is simple: the body is lighter, the brakes are faster and safer, and it is more fuel efficient. If the whole body parts of the car are made of metal materials, there should be more than one car. If there is a sudden situation on the high speed, I want to brake the brakes in an instant. Now, I can probably understand why the car bumper is plastic. But don't think that this will make the car unsafe. The overall safety of the car, the overall coordination of the particulars, not the harder the car, the safer the car.
