Information:  - The Volkswagen Beetle (officially the Volkswagen Type 1, informally in Germany the Volkswagen Käfer, in Poland the Volkswagen Garbus and in the U.S. the Volkswagen Bug) is a two-door, four passenger, rear-engine economy car manufactured and marketed by German automaker Volkswagen (VW) from 1938 until 2003.  - The Love Bug (sometimes referred to as Herbie the Love Bug) is a 1968 American comedy film and the first in a series of films made by Walt Disney Productions that starred an anthropomorphic pearl-white, fabric-sunroofed 1963 Volkswagen racing Beetle named Herbie. It was based on the 1961 book "Car, Boy, Girl" by Gordon Buford.  - Auto racing (also known as car racing, motor racing or automobile racing) is a sport involving the racing of automobiles for competition.   - In sport, racing is a competition of speed, against an objective criterion, usually a clock or to a specific point. The competitors in a race try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed to reach a specific goal.  - An economy car is an automobile that is designed for low cost purchase and operation. Typical economy cars are small (compact or subcompact), lightweight, and inexpensive to buy. Economy car designers are forced by stringent design constraints to be inventive. Many innovations in automobile design were originally developed for economy cars, such as the Ford Model T and the Austin Mini. Gordon Murray, the Formula 1 and Mclaren F1 designer, said when designing his new Murray T.25 city car: "I would say that building a car to sell for six thousand pounds and designing that for a high volume production, where you have all the quality issues under control is a hundred times more difficult than designing a Mclaren F1, or even a racing car. It is certainly the biggest challenge I've ever had from a design point of view." The alternative approach other than innovating to build a low cost car, is build a stripped down no frills version of a conventional car.  - Walter Elias "Walt" Disney (December 5, 1901December 15, 1966) was an American entrepreneur, animator, voice actor and film producer.

These films are designed to make the audience laugh through amusement and most often work by exaggerating characteristics for humorous effect. Films in this style traditionally have a happy ending (black comedy being an exception). One of the oldest genres in film, some of the very first silent movies were comedies, as slapstick comedy often relies on visual depictions, without requiring sound. When sound films became more prevalent during the 1920s, comedy films took another swing, as laughter could result from burlesque situations but also dialogue.
