The automobile industry is one of the most profitable and influential industries in the 20th century.

Cars are closely connected with our lives. It is estimated that there are about 500 million cars in the world, and on average every ten people own one. Its annual sales have hit new highs repeatedly, ranking first in the world.

This huge number reflects the popularity of cars in modern society.

Cars have always been people's main means of transportation in the past.

For a long time, it has brought people a convenient way to travel, while also broadening people's activity space.

Especially in developed countries, cars are an essential means of transportation for almost every household.

The United States has a vast territory, a relatively dispersed population, and long distances between cities. Therefore, cars have become a key means of transportation for local residents for daily travel, work, shopping, and tourism.

The automobile industry has promoted the rise of many related industries, such as steel, rubber and other industries, which have made outstanding contributions in promoting economic development.

Although cars bring convenience, they also cause a lot of troubles. In cities in some African countries, as the number of cars increases, the size of the city is also expanding, which has led to a decline in residents' living standards and an increasing number of social problems.

The number of cars around the world continues to increase, bringing with it rising energy consumption, increasing traffic congestion and worsening air pollution.

In cities, vehicle exhaust is one of the key causes of air pollution. Taking Beijing as an example, during periods of severe smog, vehicle exhaust contributes significantly to pollution.

Urban traffic congestion is a difficult problem to eradicate in some places, especially in populous cities like Tokyo, where roads are often jammed during rush hours.

As we enter the 21st century, cars and the roads they travel on are undergoing major changes.

With the development of science and technology, cars are moving towards intelligence.

Smart cars can already monitor the dynamics of driving vehicles and surrounding traffic conditions. For example, when there is a car in your blind spot, it will sound an alarm.

Automotive-related intelligent transportation systems (ITS) are also evolving.

In the future, the integration of cars and roads will be closer and more intelligent.

With the assistance of intelligent road systems, vehicles can communicate with each other and drive together. This not only enhances driving safety, but also effectively improves road usage efficiency.

When encountering a traffic accident or road construction, the vehicle will receive information in advance and can automatically choose a new driving path.

The price of microchips has dropped significantly, making the application prospects of the Global Satellite Positioning System (GPS) broad and almost unlimited.

Just like blind people can use GPS to navigate in the city.

Drones rely on GPS technology to achieve precise positioning and landing guidance. Even in dense forests, people can use GPS to determine their location.

This technology has huge potential in the automotive field.

Cars equipped with high-precision GPS chips can provide drivers with more accurate navigation guidance.

In complex urban traffic networks or remote mountain roads, GPS can still provide drivers with precise route guidance and real-time traffic conditions.

At the same time, it can also assist smart cars to achieve automatic driving functions.

Advocates of computerized highways are hopeful about its future.

This initiative helps reduce energy use, while also reducing traffic congestion, improving air quality, and enhancing driving safety.

Once autonomous driving is widely used, it will make vehicle driving more standardized and orderly, thereby reducing the incidence of traffic accidents.

Intelligent dispatching of vehicles effectively improves road usage efficiency and helps reduce traffic congestion.

Intelligent traffic light systems in some cities adjust the changing time of traffic lights by monitoring vehicle flow in real time to improve road traffic efficiency.

Moreover, the use of new energy vehicles combined with intelligent systems can greatly reduce exhaust emissions.

Buses are an important component of public transportation. Improving their frequency and operation level will have a positive impact.

Recently, the bus running intervals in some areas have been optimized. Originally, there was one every 15 minutes, but now there is one every 12 minutes.

This improves the convenience for residents to travel by public transportation.

Improving the quality of public transportation can not only meet the daily travel needs of citizens, but also effectively reduce the frequency of use of private cars in the city.

After London and other major cities have increased their investment in public transportation, many citizens are more inclined to take subways and buses when traveling, which has alleviated the city's traffic congestion and air pollution problems to a certain extent.

The development of automobiles is not only driven by industry and technology, but individuals also have an important impact.

In the automotive field, engineers conduct detailed research and design on every automotive component to continuously improve the overall performance of the vehicle.

Divers wait for instructions on the springboard to prepare to take off, and they need to have accurate judgment. Similarly, when driving a car, the driver's driving style and the speed of adapting to new technologies will also reflect the level of car development in reality.

If drivers can actively learn and effectively use the intelligent auxiliary equipment on the car, such as automatic braking and other functions, driving safety can be effectively improved.

Consumers' demand for cars also affects the production and progress of cars. For example, now, people's demand for new energy and environmentally friendly models is rising, which prompts car manufacturers to increase research and development and production in this field.
