随着时间的推移，人们开始质问飞车为什么还没出现？这是对现实的失望，因为现实无法满足对未来最激动人心的预测。当然，我们的口袋可以装下微型超级计算机，工作台上的扬声器可以讲笑话，但我们的汽车仍然是四轮驱动的。

这种情况可能很快就会改变。真的。在过去的十年里，曾经被称为“飞行汽车”的技术出现了一系列的创新；现在它们是垂直起降飞行器、电动垂直起降飞行器或空中出租车。它们是由零散的初创公司和传统航空航天公司建造的。这些初创企业来自硅谷、匹兹堡、斯洛文尼亚和中国。没有一个科技亿万富翁的投资组合是完整的，除非他投资了一款可以在天空中行驶的汽车。

如果最雄心勃勃的预测是准确的，那么在未来五年内，某些地方的人将会嘲笑那些地面上陷入交通堵塞中的人。但最雄心勃勃的预测很少是准确的。更有可能的是，飞行汽车要普及还需要几十年的时间。如果真的是这样的话，它们也不会是我们现在想象的那样。

卡内基梅隆大学机器人研究所的研究教授Sanjiv Singh表示：“普通人通常会想到一个类似于电影《杰森一家》的世界。汽车从他们的车道上起飞，然后将他们带往目的地。这种是在在人口密集、非常复杂的地区运行的车辆。”

Singh说：“我们首先看到的是自动飞行汽车向偏远地区运送货物，或者向难以进入的灾区运送救灾物资。在某个道路被飓风或者地震摧毁的地方，由于电力中断，道路损毁，物资供给无法获得。”

一旦飞行汽车进入城市，它们看起来会更像直升机或人体大小的无人机。它们会从一个停机坪垂直起飞，然后降落在另一个停机坪上。在早期，会配备一名飞行员，但人类飞行员最终会被一种更可靠、更有利可图的自动飞行系统所取代。

“它们将成为多模式运输体验的一个元素，”德勤航空和国防主管Robin Lineberger说。“但它们不能解决旅途的第一英里和最后一英里问题。”

这种会飞的汽车能够在公路上驾驶也能在空中飞行，并且可以停放在车库中，但这种车只有超级富豪才能消受得起。这并不仅仅因为它们会很昂贵，并且用户还需要维护、储存和着陆的能力，这需要的不仅仅是一条车道。Lineberger 说：“这种车型不是针对大众的。”

With the passage of time, people began to question why the flying car did not appear. This is a disappointment with reality, which cannot satisfy the most exciting predictions of the future. Of course, our pockets can hold minicomputers and speakers on the workbench can tell jokes, but our cars are still four-wheel-drive.
This situation may soon change. Really? Over the past decade, a series of innovations have emerged in technologies once known as "flying cars"; now they are vertical takeoff and landing vehicles, electric vertical takeoff and landing vehicles or air taxis. They were built by scattered start-ups and traditional aerospace companies. These start-ups come from Silicon Valley, Pittsburgh, Slovenia and China. No technology billionaire's portfolio is complete unless he invests in a car that can run in the sky.
If the most ambitious predictions are accurate, people in some places will laugh at people who are stuck in traffic jams on the ground in the next five years. But the most ambitious predictions are rarely accurate. More likely, it will take decades for flying cars to become popular. If that were true, they would not be what we now imagine.

Sanjiv Singh, a research professor at the Robotics Institute at Carnegie Mellon University, said: "Ordinary people usually think of a world similar to the movie The Jasons. Cars take off from their lanes and take them to their destinations. This kind of vehicle runs in densely populated and very complex areas.
Singh said: "The first thing we see is that automatic flying vehicles deliver goods to remote areas or relief supplies to hard-to-reach disaster areas. Where a road is destroyed by a hurricane or an earthquake, supplies are unavailable due to power outages and road damage.
Once flying cars enter the city, they will look more like helicopters or human-sized UAVs. They take off vertically from one apron and land on another. In the early days, there would be a pilot, but human pilots would eventually be replaced by a more reliable and profitable automatic flight system.
"They will be an element of the multimodal transport experience," said Robin Lineberger, Deloitte's head of aviation and defence. "But they can't solve the problem of the first mile and the last mile of the journey"
This kind of flying car can drive on the road and fly in the air, and can be parked in the garage, but only the super-rich can afford it. This is not just because they are expensive, but also because users need the ability to maintain, store and land, which requires more than just a lane. "It's not for the masses," Lineberger said.
