There are several reasons why car bumpers are made of plastic:

1. Safety. Plastic bumpers have some elasticity, which can absorb impact energy during a collision, reducing the damage to pedestrians and vehicles.

2. Weight. Plastic materials are lighter than metal materials, which can reduce the overall weight of the car, improving fuel efficiency.

3. Production cost. Plastic materials are less expensive than metal materials, which can reduce the manufacturing cost of the car.

4. Ease of repair. Plastic bumpers are usually not seriously damaged in a collision and can be repaired to their original condition.

Overall, plastic car bumpers have more advantages than metal bumpers and are widely used in the modern automotive industry.
