And flying cars. Jetsons lied.

That should finally be close? Just add drones and self driving cars together. Soon we will have drones to deliver larger stuff than a small package from Amazon, so all the basic parts will be there. Take a drone which can carry two people's weight and put a transparent box with a door on it. Add small wheels and some minimal parking capacity. Add a parachute for emergencies. (Note that there won't be a long educations for pilots. You just choose an address in Google Maps. If the drone can land vertically you might have to select a flat area at the destination, but it should be negotiated (along with parking fee) before going there.) Instead of flying cars I'd rather have the cheap launch capacity of the Shuttle, which must have set some record when it was ~ two orders of a magnitude more expensive per pound than promised. :-( With so low launch costs we would finally get real giant space telescopes and an industrial infrastructure outside the atmosphere.

  You're describing a small autonomous helicopter. (We have lots of experience with the helicopter part at least.)

    That was my explicit point in the first two sentences. The parts are here. Add a transparent box to a soon existing drone, add self-driving and you have a flying car. Military drones fly themselves already. There will be routing systems for drones when e.g. Amazon starts to deliver packets to the home. And so on. (But not necessarily helicopter. Note the "If the drone can land vertically". You could do this with a drone air plane. If the transparent box (passenger compartment) is moved automatically to/from an automated taxi to a drone, you have a point-to-point taxi service anywhere.) Edit: The next logical step is a trailer home with solar energy -- move it anywhere with a taxi large helicopter airlift. Drones deliver groceries, while you enjoy the view from your mountain top, far from any roads.

Flying cars are one of those things that make sense until you think about them carefully and with the benefit of hindsight. I wonder what our "flying car" is now in 2016.

  What doesn't make sense? The Transition looks fairly OK, though it probably only suits flying to places that are small and don't have rental cars. Flying car now is a better idea, if they're automated. More complicated flight systems are no problem for software. And safety will be far better than humans. Though if we get fully automated roads/cars, the speed improvement might not be so big. (Automated roads might be able to go at what, 200Kph? More on highways?)

    Flying cars are a horrible idea. Flying requires a 20x higher energy output than driving. It's extremely weather sensitive. It requires space for landing, unless you go VLTO, then your energy usage skyrockets even more. There are huge privacy concerns, last mile and noise issues. Not to mention it would be a further move from mass transit to (much less efficient) private transportation.
    - MichaelGG 10y ago
      I just see it as a personal plane that doesn't require a taxi or rental car. If they were more common, then the limited amount of space needed for a light-car runway would be easier to pop in. Also note that Jetsons, to use a fictional example, had no qualms about building up, in comparison to apparently everyone in the West.

      I'm not sure that's always the case. Take a look at the PAL-V, which is in production right now (there was a short item on it on Dutch TV, they're currently looking for investors to boost international sales). According to their specifications [1], it can do 6 km/l when flying, and 12 km/l on land. The specs they give aren't directly comparable sadly, so I had to do a short calculation to get the flying mileage (180 km/28 l), but it suggests that your 20x figure is one order of magnitude too high. The vehicle's range also suggests a 3x difference, not 20x. [1] http://pal-v.com/the-pal-v-one/specifications/ http://pal-v.com/the-pal-v-one/specifications/

As someone who did a pilot's license, real flying is pretty complicated at the moment by the time you've checked 20 things, radioed air traffic control etc. To get a movie flying car like experience I think you'd need self driving car type AI to deal with that stuff. Which could happen before long.

    But here the problems are clearly in the laws. Don't complain to the engineers where the flying cars are, but complain to your representative for deregulation in the laws.

      And then complain about evil government not doing enough about half-ton metal bricks falling out of the sky and killing people. Humans are too dumb to be able to drive cars safely, as evidenced by over a million people dying in traffic accidents each year. That the air travel industry has so little accidents is a miracle, and in big part owed to all those pesky and annoying regulations that can coordinate thousands of people on the same task and make them do their jobs right.
