The greatest achievement of the 19th and 20th century is the invention of the car. The automobile has become a bases of transportation across land. Cars have the power of hundreds of horses allowing people to not have to take care of horses to use them for travel. Everyone needs a car to go any where that is unreasonable to walk. If no one could drive the majority of the businesses and places to far to walk would not be used. Now since the assembly line has been used cars are mass produced and everyone can get one.
The making of an automobile takes hundreds of people. A whole factory is needed just to construct the car but the planning of the car takes great minds and big ideas of improving the car. The car starts out as an idea which is turned into a drawing. The drawing is shaped out and turned into a shell. A chassis and motor set up are made before the body or shell is put on. The right balance of weight, power, and design are what makes the cars such a big achievement in the world.
The majority of transportation around the world is by vehicle. When the first car was made no one could afford it, but now since the assembly line there are millions of cars on the roads today. Its the most convenient and cheapest way to travel. Cars are versatile as well because a car does not always have to be used on a paved road. Off road cars, war machines, and tanks are big parts of the cars world and have been used to shape countries and help people across the world.
Cars are also customizable now making it an even more comfortable way to travel as well. A driver could turn there car into a travel machine or just something to get to point a to b in the fastest time possible. The interior to the exterior are all customizable to make the car something the driver enjoys, because they wil be spending so much time in it anyway. The car is the greatest achievment of the 19th and 20th century because of what has done and what it can do for the world.
