The main function of a bumper is to protect the car's body in a slight collision, typically at parking speed. The bumper structure on modern automobiles generally consists of a plastic cover over a reinforcement bar made of steel, aluminum, fiberglass composite, or plastic. In most jurisdictions, bumpers are legally required on all vehicles.
Googleâs latest prototype vehicles originally came without a steering wheel and didnât feature brakes that were operable by its human passengers, although it was forced to add such controls so it could legally test the cars on the road. Fordâs pedestrian detection uses two sensors: radar in the bumper and a camera on the windshield. The radar detects an object, and the camera can determine if it is a person crossing the road. When the vehicle detects a pedestrian, it will warn the driver with a light and a sound.
