Automobiles are motor vehicles that transport passengers and are usually powered by an internal combustion engine using a volatile fuel. These engines are usually fueled by gasoline (petroleum), but diesel or electric motors can also be used to power cars. The modern automobile is a complex technical system that includes numerous subsystems that perform specific functions, such as control systems and electrical equipment. Each of these subsystems is based on breakthroughs in technology, such as electronic computers and advanced alloys and high-strength plastics. The design of the vehicle is influenced by factors such as environmental regulation and safety standards, government legislation, passenger comfort requirements, performance expectations and price.
The development of the automobile has had a major impact on society. It has allowed people to live farther away from where they work and it has transformed the world’s cities. The automobile has also spawned many businesses such as garages, service stations, insurance underwriters and car dealerships. Today, cars are the primary mode of transportation in most countries around the world.
PROS: Cars give people freedom to travel far distances and to visit friends. They can also make it easier to switch jobs and to move between cities. The automobile has created a global industry that provides millions of jobs. Many of these jobs are in factories that produce cars or in gas stations, restaurants and motels that serve travelers.
CONS: One of the biggest problems with cars is that they pollute the air we breathe. They can also be dangerous to other people, especially when they are involved in road accidents. Also, they are expensive to maintain and it can be difficult to find a parking space in the city.
There are special automobiles for different purposes such as fire engines, ambulances and patrol cars. There are also vehicles that can carry loads, such as crane cars at construction sites and fork-lifts in warehouses.
AUTOMOBILES IN THE FUTURE: The automobile is becoming a computerized machine that may someday drive itself. It may use sensors to detect other cars and obstacles in the path. It could also be programmed to take the shortest route to its destination. This would help to reduce traffic congestion and to save energy.
Some people worry about the safety of these cars, but they are safer than other modes of transportation such as airplanes and trains. In fact, fewer people die in car accidents than in airline crashes or in railway accidents. The most important thing is to wear seat belts and not drink and drive. Drivers should also follow the speed limit and be aware of other drivers. They should also be careful not to park their cars in front of a fire hydrant or on the sidewalk. Finally, they should always keep a first aid kit in their car. They should also have a spare tire and a tool kit in case they break down on the road. If they have a cell phone, they should try to get help as quickly as possible.
