When it comes to resource allocation, there is no choice but to speak of cars. It is possible to sit 4-5 people in the domestic car-like cars, and it is rare to see cars that take 2 people. In most cases, the back row of cars is empty, which results in the waste of resources. Therefore, parking spaces are insufficient in many places. If the car is made smaller, for example with only two seats, would it be better? There are many small, low-end electric vehicles nowadays, but the mainstream brands of small cars are not common. Why is this? Energy consumption Although the weight of the car is light, it is often because the car body is short (it will greatly increase the drag coefficient), and it tends to make up for the small car, but the height should be a bit larger (increase the frontal area), so the aerodynamic design of the car body is often not good enough, that is, as the saying goes. Not streamlined enough. Taking SmartForTwo as an example, the drag coefficient is as high as 0.345. In contrast, in the compact car, the drag coefficient of Volkswagen's 7th generation golf is 0.27, while that of Toyota's 4th generation Prius is as low as 0.24. Such a large drag coefficient makes the smart wind resistance at mid-high speed offset the advantage of heavy weight, and the high-speed fuel consumption is even higher than ordinary cars. Manufacturing cost If you only miniaturize the car from a 5-seater to a 2-seater, but you maintain the original quality level, I am afraid that the price can not be reduced too much. Take the two-car SmartForTwo as an example. The car is 2.7 meters long and its official price in Germany is 10,495 euros. It can only take 2 people. And as long as you spend 660 euros, you can buy a long 3.5 meters Smart ForFour. The volume of the latter has increased by 27%, but the price has only increased by 6%. And as long as you spend 1500 euros, you can buy a small car Skoda Jing Rui, the official starting price of 11,960 euros, 4 meters long, can ride more comfortable 4 people. At the same time, because of the increase in wheelbase, comfort at high speeds will increase. Smart sacrificed 31% of the volume, reduced 60% of the seats, but it was only 12% cheaper. It was somewhat worthless. 3. Parking space Parking is similar to driving roads. Regarding the planned parking spaces, regardless of the big car or the small car, the number of stops should be several. For off-street parking without a parking space, it seems that there will be some use. But unless you change all the cars into small cars, if there are big or small cars, the empty car after the small car leaves may not stop and is completely wasted. Although the empty car after the departure of the cart can be stopped, there is still waste. 4. Traffic congestion In fact, the car has no way to improve traffic congestion. In the process of driving a private car, the road area is mainly occupied by the need for a safe distance between the car and the car. This space is much larger than the space occupied by the car itself. For example, if a Chinese car takes an average of 83 square meters of road area, if it is shortened by 2 meters and becomes smart, it will probably take up less than 4-6 square meters, which has little effect on road congestion. And if there are a large number of cheaper two-seater cars, the total car ownership may increase. Instead, it may increase congestion. Passing the traffic lights when there is extreme congestion, because the distance from the car is small, it may be obvious that the benefits of the car on passing efficiency will be obvious, but this also requires the driver to be able to follow the start of the car. Postscript: After analyzing the above reasons, we can conclude that although the footprint of the 2-car personal vehicle is small, it does not improve other aspects. By red dot, machine can make sure the right loaction then marking on the surface of the item. Because machine working easily with high efficiency, it widely used in many fields, like marking on the kitchen tool,medical device, bathroom equipment and other industries. Besides, this kind of machine when working can not make any pollution, so we trust, it can use in our life more and more in the future.
