[飞行汽车  问答]  近日，据浙江吉利控股集团消息，其旗下全资子公司美国Terrafugia研发设计的全球首款飞行车，已开始接受私人预订。吉利集团方面介绍称，截至目前，公司已成功开发出多辆运行良好的飞行汽车原型车，计划于2019年在美国正式上市。据吉利方面介绍，吉利还计划于2023年推出全球首台垂直起降的飞行汽车。

1、从驾驶技术考虑，飞行比自动驾驶要求更高，自动驾驶只需要AI足够智能化，足够成熟就可以上路。飞行汽车你得会“开飞机”吧！现在很简单的遥控无人机还需要考证，飞行汽车更需要考证了，而且肯定比驾驶证要难得多。

2、从国家安全考虑，飞行汽车如果用于搞破坏，威力大的多，而且基本防不住。国家在没有确切有效的保证飞行汽车可控的情况下，是绝对不允许飞行汽车运行的。

3、从制造技术考虑，自动驾驶的技术渐趋完善，而汽车飞行技术现在基本上仍停留在纸面上。不管从引擎，能源消耗，可靠性等哪一方面来讲都没有跟确切的定论，仍然处于研究阶段。

4、飞行汽车不是小型飞机，小型飞机早就有了。而飞行汽车就要求桨叶足够小。而这么小的桨叶还得把两吨重的汽车个人升起来，不仅对引擎技术要求很高，就是对能源也是挑战。总不能指着那一油箱的汽油吧！估计刚够起飞两次的。

“空中飞行汽车既存在技术方面的挑战，也存在社会用户方面的挑战。”Udacity飞行汽车开发项目负责人Jake Lussier指出，“从社会用户方面而言，如何让飞行汽车系统落地到城市基础设施中去，这需面临整个社会层面的挑战。同时，让大型飞行汽车自动、安全地出行本身，也存在技术瓶颈。”

Recently, according to Zhejiang Geely Holding Group, the world's first flying car developed and designed by Terrafugia, its wholly owned subsidiary, has begun to accept private bookings. Geely Group said that up to now, the company has successfully developed a number of prototype flying cars, which are scheduled to be officially launched in the United States in 2019. According to Geely, Geely also plans to launch the world's first vertical take-off and landing flying car in 2023.

1. Considering the driving technology, flying is more demanding than autopilot. Autopilot only needs AI to be intelligent enough and mature enough to go on the road. Flying cars, you have to be able to "fly" it! Now the very simple remote control UAV needs to be tested, the flying car needs to be tested, and it must be much more difficult than the driver's license.
2. Considering national security, flying cars are much more powerful and can hardly be prevented if they are used for sabotage. In the absence of precise and effective guarantees for the controllability of flying vehicles, the state will absolutely not allow flying vehicles to operate.
3. Considering the manufacturing technology, the autopilot technology is gradually improving, while the automobile flight technology is still basically on paper. Regardless of the engine, energy consumption, reliability and other aspects, there is no definite conclusion, it is still in the research stage.
4. Flying cars are not small airplanes. Small airplanes have existed for a long time. Flying cars require small blades. Such a small blade has to lift up a two-ton vehicle, which not only requires high engine technology, but also challenges energy. You can't point at the gasoline in that tank. It's estimated that it's just enough for two takeoffs.

"Air-flying vehicles have both technical and social challenges" Jake Lussier, head of Udacity Flying Vehicle Development Project, points out that "from the social user perspective, how to land the Flying Vehicle System in the urban infrastructure needs to face the challenges of the whole social level. At the same time, there are technical bottlenecks for large flying vehicles to travel automatically and safely.（文/飞行汽车 www.feiauto.com）
