Flying cars
Since a lot of you forum posters are really good in problem solving, how would you guys suppose flying cars will change traffic? What kind of methods do you find it possible to make such a ridiculous contraption (as we would see it now)?
What problems would it pose? What of air traffic? Parking? Accidents? Safety precautions? So, how would you suppose we could perform it, and if possible... is it a good or a bad idea? [let's make it a poll, Flying cars GOOD: Flying cars BAD]. |

Re: Just a thought...
I can't even begin to state how ludicrously inefficient and useless flying cars would be. For any even remotely short travel distance, they'd be nigh useless, and for sufficiently long distance, planes already come in small sizes for personal use.
I suppose you might be meaning -hovering- cars? That might make a little more sense as a "Future WOW!" technology to be figuring might be forthcoming. Last edited by devonin; 12-22-2008 at 09:11 PM.. |

Re: Just a thought...
Regardless of its efficiency, they would undoubtedly create enormous amounts of pollution that would be even more detrimental to Earth's survival. I mean, they could be efficient if, in theory, half the population used "land cars" and have used "air cars." That would refuse ground traffic by about 50%, also assuming their cost was equal to ground cars. Also, how would you regulate the air traffic? Firstly, we'd need, what, skyhooks, to leave markings for directions. Second, you'd need to secure the safe travel of plane to car ratio. I mean, in general, you'd have an entire road system in the air. So, how do we get all the objects on the road to float? Parking wouldn't be a big issue, it would be the same as now.

As for hovering cars, the problem with that is that we would need to make an all directing repelling force upon the car so the tilt of the car doesn't make it easy to knock over and cause disaster. You also have to take into account what the costs could possibly be (or even health problems it could impose) to have such a car. The main purpose of me making this thread is to discuss flying cars as such. You know, point out some things I didn't really think of at first. (: (edit): Quote:
Parking is an issue when you need to figure where to go from air to ground. The thing is, you can't just drop into a parking zone... That poses multiple safety problems, and you can't just land next to a parking zone for nearly just the same reason. Also, what kind of thrust would we need to lift a car into the air, considering its size, weight, etc.? What kind of methods of lifting would we need to make such a thing possible at its safest? Even if it's not a good idea to attempt... (edit 2): Back at devonin, personal jets can be too expensive for practical use. That doesn't mean, however, that you can't make them cheaper.

Re: Just a thought...
I didn't say anything about personal jets, I said personal aircraft. The kind of thing that seats like many cars do: Two people, maybe a third or fourth if they squeeze. When you say "Personal Jet" I'm picturing 'Air Force One' for just me to use. I mean the kind of small aircraft that you get lisenced to fly yourself (And which you can get at 17 years old) and it would be easy enough, if that sort of thing became more widespread, for people to start operating aircraft rental businesses at major airports.

I see where you're going, but the costs of these things and go up to millions of dollars... which isn't practical for every day use of the normal person... (in terms of economics). Personal Aircraft's can be considered flying cars, but learning to drive a "flying car" (as many people interpret it) will take less learning to drive, and a high population of Americans don't want to learn something harder to use. Although, I do see where you're going with this... in fact, it's the first time I've heard of an aircraft. So, thank you for the information. |

Re: Just a thought...
I mean things like this
My point is that any "flying" vehicle, even things with VTOL capability (helicopters etc) would just be not at all efficient for short distances of travel. And for longer distances, aircraft like the above one already exist to move smaller numbers of people over long distances in the air. I simply deny that airborne vehicles for personal use would ever become "practical for every day use of the normal person" to use your phrase. |

Also, if there are any collisions in mid-air, you'll have 2 cars crashing to the ground, and would have the potential to destroy buildings and kill more people. You don't hear of two jets colliding very often since few people use them, but commercializing flying cars would increase the rate of car accidents. And it would probably use more fuel and will cause gas prices to go even higher. Last edited by dynamite1; 12-23-2008 at 11:08 AM.. |

I am not supporting flying cars at all. On the contrary, I'm against them being produced. This was meant to be a more pro/con kind of question. I didn't notice it wasn't clear, it was kind of late when I made it. |

I wasn't referring to speed of arrival, I was referring to the fact that you need a large and open space to allow aircraft to take off and land. If you had to taxi your personal flying car for half an hour out of town to get to a strip you could take off from, it would rather defeat the purpose. Quote:

Re: Flying cars
Well, if cars could easily and efficiently hover over buildings etc we could have a much more effective transport system.
Obviously, the entire system would have to be controlled by computers. Every car would have to be piloted by a computer(s) that monitor the entire system for a given area. It could be incredibly effective, given there would be no need for traffic stops etc so you could get from one place to another very quickly. Traffic stops and accidents could be removed entirely with a completely computerized transit system, given the only reason they exist are because of human error or simple inability while driving. As such, I would think such hover cars could be more eco friendly than current cars assuming the technology was available to pull this off. We have quite a ways to go before such technology will exist, though I can see computer controlled transport in the not too far off future.

Re: Flying cars
Let's just imagine it -- Drunk air accidents. No more needs to be said.

Only in your imagination can you make it possible with modern knowledge... You need to have a repelling gravity force to control the balance of hover car, in which would require a lot of work, just for a test that may not even be successful... Flying cars COULD happen, but they don't and for a good reason. (edit): computers crash all the time, by the way... |

Accidents wouldn't become a large problem - they'd probably be greatly reduced, actually. You'd typically be nowhere near other vehicles, and I'd guess that proximity is one of the largest factors contributing to accidents. I think the main pro to this would be greatly increased residential opportunities in cities. The roads could be cut down a lot, and the area gained can go to more housing, parks - anything, really. Why are you against the flying car, MDMA? Besides the obvious problem of our energy-harnessing abilities not being ready for this big an increase in demand, what could be bad about them?

Re: Flying cars
The only arguments I can find, and are probably already said, are the fact that MAJOR airways would have to be created and mapped, somehow navigated, and if that even works through a system of floating buoys or some digital gauge, the chances of you surviving an air crash as opposed to a land crash is a lot worse.
The pollution factors, cost factors and such are also a negative point on the idea, although it is fun to think of randomly futuristic ideas once in a while, in reality we all aren't going to be wearing silver shiny jumpsuits and driving air cars to Mars. Besides, ground vehicles have a LONG way to go before the technology begins to see any form of perfection. Enough said |

Re: Flying cars
I think that the people who are against flying cars are not using their imagination enough when thinking about what may be possible. I'm not going to be talking about current hovercars or personal airplanes or helicopters. These aren't used today for obvious reasons. I've treated the question as hypothetical, and I'm imagining doc's car from Back to the Future.
If we could find a way to make fairly quiet, not incredibly polluting flying cars, it would be awesome. The biggest improvement would be the elimination of highways. They're expensive to build, upkeep, keep clean, and they take up a lot of room. By comparison, developing a MAP which requires no maintenance would be great. It actually wouldn't be that bad to make a map either. Here's one possibility: Altitude could be divided into layers. The bottom one could be for the slowest traffic, middle one for mid-speed, etc. Each layer (however many we'd want) would then be divided into sub-layers for different directions. Since we're restricted by roads, there could be, oh, say, 20 (just for example, it'd need to be looked at much more closely, obviously) different sub-layers, or horizontal directions one can take in any layer. The trickiest part would be changing layers or sub-layers, but it'd still be doable. For sub-layers, if the sub-layers were layered in order, (so have 0 degrees on the bottom, then 18 degrees above, then 32 degrees, etc.), you'd simply put enough vertical distance between each of the sub-layers to change direction, to be able to make an easy turn while changing altitude. For moving between layers, you'd have to leave a little more room so one could easily slow down or speed up safely, and put the layers so that when you transfer layers, you stay facing the same horizontal direction. If you were looking on this from the top-down, you'd see layers of traffic all moving the same direction, with the slower traffic on the bottom, and the faster traffic on top. My only concern would be that depending on how many directions you'd want defined, and how many different speeds defined, it might become very high in terms of altitude. The cars would obviously have built-in altitude detectors, and would ideally also be able to drive themselves once you've determined the speed you want to go at and the place you want to go. You'd probably still want to land and take off manually though, and be able to manually control the car just in case. The lowest heights would basically be a slow 'free for all', kind of like a parking lot. You'd also have to either make the layers start at an altitude higher than the tallest building, or have specific 'no fly' zones in areas with tall buildings. I like the 'no fly' zone idea better, but in large cities with tall buildings where traffic's heaviest, the type of flying I've suggested wouldn't seem to work well. Regular aircraft would probably still be used with this system though, because the further away you want to go, the less likely you can be to fly from point A to point B, because there's only so many directions you could go. You would have to make sure cars can't fly near airports then. Also, airplanes are designed to withstand the changes in pressure you get at high altitudes. Regular flying cars probably wouldn't be. I suppose if this map were to get too high, you could take out the speed layers and instead have speed lanes, just like we do now. They'd be repeating lanes though, so maybe have 10 lanes or something, then a space, then another 10 lanes. This would also give room for emergency vehicles, as they could have their own lane.

Re: Flying cars
bad idea, to put it simply, flying car accidents will always be fatal.
