据国际能源署估算，全球有16%的碳排放来自汽车排放。虽然很多人寄希望于新能源汽车解决环境问题，但从全球汽车销量数据上来看，2018年全球汽车总销量达9500万辆，只有不到1%是纯电动车。国际能源署预测，温室气体排放情况在未来30年不会有太大改观。另一个制约因素是道路基础设施。到2050年，世界总人口预计将达100亿，城镇化水平65%，但城市只占地球面积的3%。在过载人口后，城市会有更多的路，但“流动”速度也会随之减慢，从而带来拥堵。

顾名思义，垂直起降飞行器可以在大厦顶楼或城市空地原地起飞降落，无需地面跑道。美国穆勒飞行车的中国代表Shanley，与直升机相比，eVTOLs的安全性与性价比更高，“它eVTOLs比直升机速度快3倍，但不用完全依赖外置螺旋桨”。而且直升机叠加直升机停机坪造价在千万元至亿元不等，“在美国生产的话，一架eVTOL也就50万美元。”网大为认为，这种有别于私人飞机和传统直升机的飞行器，可以成为大众的交通方式。

According to the International Energy Agency, 16% of the world's carbon emissions come from cars. Although many people hope that new energy vehicles can solve environmental problems, according to the global car sales data, in 2018, the total global car sales reached 95 million, less than 1% of which are pure electric vehicles. The IEA predicts that greenhouse gas emissions will not change much in the next 30 years. Another constraint is road infrastructure. By 2050, the world's total population is expected to reach 10 billion, and the level of urbanization is 65%, but cities only account for 3% of the earth's area. After overloading the population, there will be more roads in the city, but the speed of "flow" will also slow down, resulting in congestion.

As the name implies, vertical takeoff and landing aircraft can take off and land at the top floor of the building or urban open space, without the need for ground runway. Shanley, the Chinese representative of the American Mueller flying car, compared with the helicopter, evtols has higher safety and cost performance, "it's three times faster than the helicopter, but it doesn't rely on the external propeller completely". Moreover, the cost of helicopter overlay helipads ranges from 10 million yuan to 100 million yuan. "If it is produced in the United States, one evtol will cost 500000 dollars" According to netdawei, this kind of aircraft, which is different from private aircraft and traditional helicopters, can become a public mode of transportation.（文编译/飞行汽车 www.feiauto.com）
