The invention of the automobile revolutionized the world in ways that few other technologies have. Modern life seems almost inconceivable without access to a vehicle. It has shaped urban design, reshaped government services such as police, fire and roads, created new businesses such as gas stations, hotels and amusement parks, and allowed people to visit distant cities, towns, and countryside in ways that were not possible before. In the United States alone, cars travel more than three trillion miles (five trillion kilometres) each year.
Cars are a symbol of freedom and independence. They give people the opportunity to go wherever they want, whenever they want, and to take their loved ones with them. They also make it easier for people to reach far-away friends and family members. The car is a powerful tool for social and political change, and it was instrumental in advancing women’s rights and the cause of civil rights during the 1910s and 1920s. Women who had no other means of transport were able to drive and campaign for the vote, allowing them to be fully active participants in society.
Cars have thousands of individual parts that are arranged into several semi-independent systems to perform specific tasks. These systems include the body, chassis, engine, and drivetrain. The automotive industry’s research and development engineers are constantly improving these components to make the vehicles faster, more fuel-efficient, handle better, keep occupants safer, and reduce noise and pollution. New technological developments are being incorporated to meet these demands, and the branches of engineering that deal with these improvements are called Automobiles Engineering.
