Advantages of the car:
1. Bring the convenience of transportation, in today's era of efficiency and time is money, the convenience of transportation brings huge benefits to human beings, reducing unnecessary travel time.
2. Brought the appearance of comfort, not afraid of wind and rain, the past bicycles, electric vehicles, motorcycles in the bad weather environment, not very easy to use, the arrival of the car undoubtedly solved these problems.
3. In many cases, the car is a status symbol, do you have a house? Do you have a car? Undoubtedly, having a car is a point of inquiry that represents whether you have money or not. A good car is a reflection of your identity, status, and assets.
Personally, I think that the biggest advantage of the car is that it brings convenience to people.
In 1769, the Frenchman N.J. Cugnot built the world's first steam-powered three-wheeled car. In 1879, German engineer Karl Benz successfully tested a two-stroke experimental engine for the first time. In October 1883, he founded the "Benz Company and the Rheinland Gas Engine Plant", and in 1885 he built the first Benz patented motor car in Mannheim, which was a three-wheeled vehicle with a two-stroke, single-cylinder horsepower gasoline engine, which had some of the basic features of a modern car, such as spark ignition, water-cooled circulation, tubular steel frame, leaf spring suspension, rear-wheel drive, front-wheel steering, and brake handlebars.
On January 29, 1886, German engineer Carl Benz filed a patent for his motor vehicle. In October of the same year, Karl Benz was granted a German patent for his three-wheeled motor vehicle (Patent No. 37435A).
This is what is considered the world's first modern car. For these reasons, 1886 is generally regarded as the first year of the automobile, and some scholars regard the year when Karl Benz built the first three-wheeled car (1885) as the year of the birth of the automobile.

Do you think about it this way, the car is one of the major inventions of mankind, and it is also one of the most important tools of land transportation at present, which brings great convenience to people's life and production, such as: replacing the work that people themselves cannot or are not easy to complete; shorten the time required for the movement of objects (people, money, things, etc.) between two points and improve work efficiency; Reduce the physical exertion of people when traveling, especially when traveling long distances; Move comfortably. Of course, there are still unsatisfactory places in the current design and manufacture of cars, such as the car driving is closely related to the road, once the road condition is not good, the vehicle will be obstructed, and the vehicle will not be able to pass in serious cases; Vehicle driving safety is mainly controlled by the driver, once the driver is not focused or fatigue driving, there may be safety problems; When there is a traffic jam, it is impossible to get rid of it on the two-dimensional plane; There is still room for significant improvement in its ergonomics, comfort, and safety.
But I believe that with the advancement of technology, the performance of the car will be better, and people will like it more.

For golfers who are good at spinning the ball, it is more advantageous to play on the dirt field. >>>More
