[飞行汽车  新闻]  飞行汽车的安全始终令人担忧。尽管吉利Transition宣称通过了美国航空管理局和国防部安全测试，但目前飞行汽车市场的整体安全系数依旧波动不止。近期，据外媒报道，一家名为底特律飞行汽车公司（Detroit Flying Cars）的型号为WD-1的混动原型车在进行飞行测试过程中意外坠落地面，工作人员在驾驶过程中受伤。或许处于安全性考量，目前在美国，部分已批准发售的飞行汽车仅能在郊区使用。

基础设施建设的跟进也需要时间。一方面，停机坪的建设需要考虑交通、环境、人文、消防等因素，还要考虑大风、雨雪、冰雹等恶劣天气的影响。另一方面，燃油与电池的配套供给也构成问题。空客公司Vahana自动飞行车项目负责人Zach Lovering表示，目前飞行汽车电池的供电能力还不够持久，“依据电池耗电，飞行汽车可承受的使用人数为2-5人。预计电池研发进度将以每年8%的速度增长。”

尽管具备价格优势和便捷的出行体验，飞行汽车的共享出行还未形成清晰的商业模式。有媒体指出，在当前技术条件下，具有普及潜力的共享飞行器尚未出现。因此，飞行汽车的推行仍有很长一段路要走。

飞行汽车代表了终极的系统集成挑战，是工程、监管和网络管理的综合体，一众玩家仍不断在试错中磕磕碰碰前进。目前看来，诸多挑战交织下，飞行汽车落地之前，或许还要“再飞一会儿”。

The safety of flying cars is always worrying. Although Geely Transition claims to have passed the safety tests of the US Aviation Administration and the Department of Defense, the overall safety factor in the flying car market is still volatile. Recently, according to foreign media reports, a hybrid prototype vehicle named Detroit Flying Cars (WD-1) accidentally crashed to the ground during flight testing, injuring its staff during driving. Perhaps for safety reasons, currently in the United States, some of the approved flying cars can only be used in the suburbs.

The follow-up of infrastructure construction also takes time. On the one hand, the construction of the apron needs to consider traffic, environment, humanities, fire protection and other factors, but also consider the impact of severe weather such as gale, snow, hail and so on. On the other hand, the matching supply of fuel and battery is also a problem. Zach Lovering, head of the Vahana AV project at Airbus, said that the current power supply capacity of the batteries for flying cars is not long-lasting enough. "According to battery power consumption, the number of people who can afford to use the batteries for flying cars is 2-5. It is expected that the progress of battery research and development will grow at an annual rate of 8%.
Despite the advantages of price and convenient travel experience, the shared travel of flying cars has not yet formed a clear business model. Some media pointed out that under the current technological conditions, shared aircraft with universal potential has not yet appeared. Therefore, the implementation of flying cars still has a long way to go.

Flying cars represent the ultimate system integration challenge and are a combination of engineering, supervision and network management. Players are still bumping forward in trial and error. At present, it seems that under the interweaving of many challenges, the flying car may have to "fly a little longer" before landing.（文/飞行汽车 www.feiauto.com）
