Bumper car is the generic name for a type of flat ride consisting of several small electric car

Design

Power is commonly supplied by one of two methods:
  • The oldest and most common method uses a conductive floor and ceiling, each with a separate power polarity. Contacts under the vehicle touch the floor while a pole mounted contact touches the ceiling, forming a complete circuit
    Electronic circuit
    An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow...

  • A newer method uses alternating strips of metal

     across the floor separated by insulating spacers, and no ceiling grid. The alternating strips carry the supply current, and the bumper cars are large enough so that the vehicle body can always cover at least two strips at any one time. An array of brushes under the car make random contact with whatever strip is below, and the voltage polarity on each contact is sorted out to always provide a correct and complete circuit to operate the vehicle.

The mineral graphite is one of the allotropes of carbon. It was named by Abraham Gottlob Werner in 1789 from the Ancient Greek γράφω , "to draw/write", for its use in pencils, where it is commonly called lead . Unlike diamond , graphite is an electrical conductor, a semimetal...

. The car can be made to go backwards by turning the steering wheel far enough in either direction, necessary in the frequent pile-ups that occur. Most carnivals and amusement parks require riders to be at least 42 inches or taller to ride and 52 inches (1.3 m) or taller to drive the cars.

Although the idea of the ride is to bump other cars, safety-conscious (or at least litigation-conscious) owners often put up signs reading "This way around" and "No bumping." Depending on the level of enforcement by operators, these rules are often ignored by bumper car riders, especially younger children.

During their heyday (in the late 1920s through 1950s), the two major bumper car brands were Dodgem and the Lusse Brothers' Auto-Skooter. In the mid 1960s, Disneyland introduced hovercraft
