When it does not exist, design it." - Sir Henry Royce. An AUTOMOBILE, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor.The numbers are increasing rapidly, especially in China and India.Motorcycles vary considerably depending on the task for which they are designed, such as long distance travel, navigating congested urban traffic, cruising, sport and racing, or off-road conditions.Motorcycles are the most affordable form of motorised transport in many parts of the world, and for most of the world's population, they are also the most common type of motor vehicle.Most countries also have differing laws against driving whilst under the influence of alcohol or drugs.Motorists are almost universally required to take lessons with an approved instructor and pass a driving test before being granted a license.
It was designed as an expedient testbed for their new engine, rather than a true prototype vehicle. However, if a two-wheeled vehicle with steam propulsion is considered a motorcycle, then the first one may have been American.The large-scale, production-line manufacturing of affordable automobiles was debuted by Ransom Olds at his Oldsmobile factory in 1902.This concept was greatly expanded by Henry Ford, beginning in 1914.Most definitions of car say they run primarily on roads, seat one to eight people, have four tires, and mainly transport people rather than goods.Cars came into global use during the 20th century, and developed economies depend on them.Off-road motorcycles include many types designed for dirt-oriented racing classes such as motocross and are not street legal in most areas.
