Despite their potential, no one has managed to take them from flight of fancy to everyday reality
(For the Guardian version, see here).
In 1940, Henry Ford said: “Mark my words – a combination aeroplane and motor car is coming.” With flying taxis apparently on the way, it looks like he was right, but what a wait: 80 years later, “dude, where’s my flying car?” is shorthand for any stuff “they” promised us that we haven’t got.
We have always wanted to fly, so, as soon as cars came on to the scene, we wanted those to fly too, like the ancient Greeks wanted horses to fly. Early blueprints for the US interstate highway grid even had adjacent runways ready for flying cars. But those never came, and now, that concept of the flying “car” seems naive, a 20th-century dream fuelled by decades of SciFi and the Jetsons, as obsolete as the model T. Yet as we’ll see, something just as good may take its place.
The flying “car” may seem quaint because history teaches us that multi-use vehicles are naff: cars are designed for roads: who needs a vehicle shaped like a car when it can fly? What is a perfect design for an aircraft is not perfect for a car; to try to combine the two is what UK design consultant Peter Stevens calls “an inherent, debilitating compromise.’’
We learnt this lesson the hard way. Witness the foolhardy Convair Model 118, (1947) – simply a car with plane wings stuck on top. It was forced kicking and screaming into the air on two occasions, with perilous results. This tortured Frankenstein of a contraption is a super example of why your local bus isn’t amphibious, and submarines don’t fly.

Yet few people wouldn’t want a personal, car-like, flying vehicle – comfortable, convenient and liberating; not something we’ve already got, like a helicopter, or even a plane you are allowed to drive on a road, an idea making the rounds ever since the admirable, but painfully labour-intensive, 1950s AeroCar.
It’s generally agreed runways are a no-no in most urban environments, so our “car” needs to be capable of quiet, stable, vertical take-off and landing (VTOL); extremely tricky – as SkyCar veteran Paul Moller has found, “nothing comes down faster than a VTOL vehicle upside down.”
At present, that means propellers of some sort, but Dekkard’s ride in Blade Runner didn’t look like a giant drone. Similarly, anything with jets stuck on the wings feels like a plane, and besides, no one wants the noise of a Harrier taking off next door. To top it off, VTOL devours fuel, as, in the absence of a new method of levitation, we are still relying on pushing a lot of air downwards.
Technical dilemmas aside, in any future where there are flying cars, everyone will want one: motorway pile-ups are bad enough without the horrors of a 3D version. Autonomy might only be granted only to police or other emergency vehicles – as in Blade Runner.
So you won’t be a pilot, you’ll be a passenger, in a vehicle hooked to a complex GPS system, a frighteningly clever self-driving AI, and a whole new concept of air traffic control.
All of which is difficult, but not impossible.
Uber already is already well advanced into negotiating the technology and safety infrastructure in its research into Elevate, a fleet of electric, autonomous, VTOL aerial taxis, basically passenger drones, planned to launch by 2020 in Dubai, and other cities thereafter. It envisages “vertiports” in city centres, contolled by an enhanced air-traffic control. Elevate is already in an passenger drone arms race with Larry Page’s Kitty Hawk aerial taxi, China’s Ehang, E-Volo’s Volocopter and Airbus’s Vahana.
The traffic they could soon be controlling might include some of the following, some of which are like a car, some … well … less so.
Terrefugia’s Transition: Henry Ford’s “combination aeroplane and motor car” encapsulated. The Massachusetts firm says it’s “the world’s first practical flying car … making that Jetsons dream a reality”. Downsides: the Transition looks like a plane, takes off on a runway, like a plane, and you still need to be a pilot and at an airport to fly it. That’s a plane – albeit one allowed on the road by dint of folding up its wings like a metal bat. For the same price – about 230k – you could get a plane and a nice car. Available in 2019.
The Pal V-One drives like a souped-up Sinclair C5 on the road, but then laboriously unfurls cumbersome helicopter rotors and yet STILL needs a runway to take off. Nope.
From Slovakia, Aeromobil’s impressive flying car looks the part, with its super-lightweight, carbon-fibre tuck-in-able wings. But it, too, needs a runway, so it can either be used either as a car, or as a plane. Great if you live in the outback; otherwise, might as well get a car, and a plane.
Toyota is working on a fully electric, VTOL, computer-controlled flying car. At present it looks like some hairdryers nailed to a pallet, but don’t bet against Toyota having something spectacular to show off at the 2020 Olympic games in Tokyo.
Israel’s Urban Aeronautics’ uses, a more elegant enclosed rotor system on its wingless, computer-controlled Fancraft: “the classic vision of a flying car” (more a flying hovercraft, perhaps). The Israeli military has already snagged the technology for a rather sinister flying tank it calls the AirMule (for use in “search and rescue” where helicopters would be unsuitable). Easy to imagine the police aerially harrassing us with one of these within a decade.
Two examples share first prize: Terrefugia’s TF-X – an all-electric, AI-controlled, VTOL vehicle that looks much more like that car in your head, but is sadly 10 years away; and the temptingly sleek Lilium Jet – the world’s first VTOL electric jet, according the the German tech firm. Faster than a helicopter, quieter than a Harrier jump jet… even a bit like a car.
Finally, no mention of flying cars must pass without an honorable award for gallantry to Paul Moller and his stylish “volantor” – a VTOL plane-like car that started life in 1965 as a flying saucer you could drive. Fifty years later, it still awaits investment.

It’s probably a matter of when (not if) road-based travel becomes obsolete – the likes of Uber already show the will is finally there and the tech is tantalisingly close.
Regulatory hurdles aside, we may see VTOLs over our cities very soon… but whether they will allow you to drive one is another thing.
