Is the World Ready For Flying Cars? (engadget.com)

An anonymous reader shares a report from TechCrunch, adding: "Is the world ready for flying cars? Sebastian Thrun, the supposed godfather of autonomous driving, and several other tech investors seem to think so." From the report: At TechCrunch Disrupt SF 2017, Thrun talked a lot about flying cars and how that was the future of transportation. So did GGV's Jenny Lee, a prolific investor in China. And so did Steve Jurvetson, one of the original investors in SpaceX. The technical backbone for flying cars seems to be there already -- with drones becoming ever-present and advancements in AI and self-driving cars -- but the time is coming soon that flying cars will be the primary mode of transportation. "I can't envision a future of highways [and being] stuck in cars," Thrun said. "I envision a [future] where you hop in a thing, go in the air, and fly in a straight line. I envision a future where Amazon delivers my food in the air in five minutes. The air is so free of stuff and is so unused compared to the ground, it has to happen in my opinion."

Cars today are forced to move on a two-dimensional plane (ramps, clover intersections and tunnels set aside), and while self-driving cars would make it easier for cars to talk to each other and move more efficiently, adding a third dimension to travel would make a lot of sense coming next. Thrun pointed to airplane transit, which is already a "fundamentally great mass transit system." Jurvetson said he was actually about to ride in a flying car before he "watched it flip over" before arriving to talk about some of the next steps in technology onstage. So, there's work to be done there, but it does certainly seem that all eyes are on flying cars. And that'll be enabled by autonomous driving, which will probably allow flying cars to figure out the most efficient paths from one point to the next without crashing into each other.
Lee said that China is closely analyzing changes in transportation, which might end up leading to flying cars. "I do want to highlight that there's going to be huge disruption within the transportation ecosystem in China," Lee said. "Cars going from diesel to electric. China has about 200 million install base of car ownership. In 2016, only 1 million cars are electric. The Chinese government hopes to install 5 million parking lots that are electric... Even the Chinese OEMs are buying into flying taxis."

      Airplane maintenance is much more critical than automobile maintenance because of the potential for death and destruction should an airplane undergo mechanical failure. That maintenance would be very costly. Also with increased quantities of flying objects above us, the probability of crashes would greatly increase. Add to that a myriad of other things that could go wrong and my response is "NO", we are not ready for flying vehicles.

      If it's so "possible", then why aren't all airplanes currently flying themselves? Yes, I understand what auto pilot is but I also understand what it is not. That is why we have air traffic controllers. Imagine what would happen if we had millions more objects flying above us.

And coordinating thousands of those suckers including the one right around the corner of the building on your left that you can't see and that can't see you and will be wanting to occupy the same space you plan to be occupying in three ... two ... one ... seconds.

      I also agree with the comment that it may be more than 15 years before we have truly safe fully autonomous cars. Not that there won't be lots of driverless vehicles in specific applications such as long distance expressway transport before then. But a driverless car you can safely send your ten year old off to school in is a long way off.

    Is this the tech VC's version of the 7 Minute Abs pitch? "Why would anyone travel in two dimensions when they can travel in three?"

    It's a little more complicated than that. Here are some things that don't matter so much in 2D road travel but matter a lot when you're flying
    * wind, winds changing at higher altitudes, and wind shear
    * Air speed vs ground speed
    * Heading vs ground track
    * Convective weather (at takeoff, all along path of travel, and at destination)
    * Air density (at takeoff, all along path of travel, and at destination)
    * Vehicle weight for takeoff and travel, and weight changes as fuel burns
    * Lift characteristics at altitude (at takeoff, all along path of travel, and at destination)
    * Ability to descend safely if a system fails (single engine?) or you are crashed into
    * Empty gas tank doesn't fail gracefully
    * Inability to stop moving (probably)
    * Obstacles (hills, mountains, towers, buildings
    * Etc

    As someone who flies, I am (a) certain there will be some sort of flying vehicle some day, and (b) aware there is a lot to figure out. These are all obviously solvable problems because people already do fly. It's just hugely expensive and requires a lot of training (relative to driving). What we are talking about here is ModelT-izing flight which will require a lot of idiot proofing including expensive redundancy while at the same time really driving down the purchase and operational costs of flying. These are not small problems, and these problems are not analogous to the problems of autonomous driving.

    2. Re: Autonomous Vehicles by TheRaven64 · · Score: 2

      My issue is physics... do you have any idea how much energy it takes to make something fly?

      The theoretical best case: none. You gain gravitational potential energy taking off, you lose it again coming down. You gain kinetic energy accelerating, you lose it again decelerating. Practically, you probably don't get any of the potential energy back when landing, so getting a 500kg craft up to 1km requires around 5MJ (about 1.4kWh). Once you're up, it gets more complicated because you can either do the helicopter or rocket thing (displace air or propellant directly downwards to generate lift), or the fixed-wing thing of trading lift for drag.

      In terms of fuel economy, large airliners beat cars in fuel consumption per passenger-mile, but they have economies of scale (they don't, for example, beat trains) that are lost in smaller aircraft. For example, a microlight (in the UK, under 450Kg dry weight) typically gets around 10km per litre, so 10L/100km. To put that in perspective in the US, the average for cars is around 6.6L/100km, in the EU it's 5L/km. That said, planes can travel in a straight line, whereas cars often have to go a long away around obstacles to follow roads, so the numbers are a bit closer when you compare point-to-point distances.

  6. Flying cars? by RyanFenton · · Score: 5, Interesting

    If I were writing a science fiction story, I wouldn't include flying cars as an element.

    Rather, I'd just make 'travel pods' - comfortable compact living quarters equipped with entertainment/work surfaces, storage, and seats that convert smoothly into beds - all within a strict volume/weight, all in a small geo-stabilized shock mount.

    All transportation would take these pods. Cars, helicopters, boats, spacecraft, and essentially everything else. Most of these vehicles would be somewhat crude-looking frameworks compared to our current fashionable vehicles - but few would care, as the method of getting there are just details, and not the important part, very few would put any status into it.

    Going from New York to a rural town outside of Hong Kong might involve a few cars, a ferry, an ocean freighter, then a small freight helecopter (large drone-like thing) to get you to the exact house, which the passenger would rarely care about. The cost would be something similar to what we'd consider an Amazon shipping expense, regardless of the number of legs, and time roughly scales with distance.

    The biggest concern of folks traveling this way would be time taken and menu selection. All transport units would have a somewhat extensive set of diagnostic tools, with an occasional scandal for any company suspected of skirting the rather heavy regulations put on those, or in any way skirting safety mores. The failure on a redundant pod mounting arm would actually make the news, as would anything even close to death of a passenger.

    This is my guess of something closer to the actual future, based on existing trends. Folks desire focus on the things they care about, and transportation isn't as sexy as it was. They want to get there cheap, and not care about the details. Our taste for safety should also go up over time, and the whole thing deserves a bit of a push towards automation and commoditization. .

    I certainly wouldn't be sad to see our current commercial car companies/insurance going away, in favor of industrial economy-scale vehicles built to better use every resource.

    Lots of stories you could make with that concept too - from Asimov Caves of Steel-style stories with murder sub-plots, to stories of how prisons would work in such a culture.

  7. Just a few years away--kind of like AI by Tony+Isaac · · Score: 2, Interesting

    We've been hearing for decades that flying cars--and AI--are just a few years away. Right.

    For flying cars, there's still one big problem that's not even close to a solution: Battery technology is nowhere near close to being able to store enough energy to make flying cars practical. A Tesla car battery weighs in at 1,200 lbs, and it can only power a car--on the ground--around 200 miles. It takes a lot more energy to keep a one ton drone aloft.

    And then there's the problem of safety. Air traffic is routed specifically for safety, to minimize the possibility of crashes into buildings or people. With flying cars, the whole point would be to fly among people and buildings. This cannot have a good ending.

    The technology for "personal air transportation" is already available (though still rather expensive), but the technology to control that much air traffic safely is definitely not ready for prime time yet. People are working on it, though, so eventually it will probably happen. But I think self-driving cars are going to revolutionize personal transportation long before that... which will reduce the demand for flying cars.
