Has anyone here ever tried? I guess you would have to be a super nutter to think, ah that sounds like a great idea, lets do it.
I have here a prime specimen of a super nutter. It reminds me of back in the day our country had them too, but now everyone is far too sensible and such an idea would be,,... ridiculous of course.
The situation 8m ago:
The situation 4m ago
And I guess you will have to keep an eye on the channel for future progress.

Cost and energy consumption would be a problem, then there are structural issues. To fly it would have to be light, which would make it an egg shell on the roads and very unsafe. It just isn't practical.

People have tried.  People have died. The added weight of having a vehicle designed to do two things places extra strain on the spars, the AVE Mizar prototype failed and fell out of the sky for this reason. |

latest flying version and still not practical..

It would be pointless because it would do neither thing well and would use a crazy amount of energy.

Haven't watched the video but from the still pic I see when I click the link this looks a DIY version of something more robust they're up to in the Gulf states, which an acquaintance of mine who works all over the world as a geologist brought pictures and video of back from his last visit to Dubai The thing about Dubai and most such places is the streets are literally paved with gold as the top what is it 5% of the population live like kings off the oil revenue of the last 50 years, and nobody and I mean NOBODY gives a fuck about the bottom 90% of the society out there, the dregs fighting to make a living. And unless this country adopts that model, it won't have the elitism needed to enable the safe use of such toys |

That's around the proportion of the UAE population which is of foreign i.e. non-Emirati extraction.
One curious aspect of this thread is the fact that the Baron hasn't mentioned that the flying car inventor featured in the OP is ethnic Chinese but obviously based in California not China. Or that the two real cars on the driveway are a BMW and a Tesla, not a Great Wall or some such other Middle-Kingdom brand that the Baron is often suggesting we'd be sensible to opt for.
Seems that the Chinese themselves know what's good for them even if the Baron does not, and will grab it with both hands if it comes within reach.
Funny old world eh.

I would just be very surprised if the video was in a place I recognised. like a British town say. Every single post I've read so far today on here has been carping at someone or some group. This is the problem in this country. Where we used to get in our garages to build all manner of inventions, we not sit there in front of our screens finding fault with anyone who does.
The thing was I watched the video because I wanted to see how difficult it was to design and build one from scratch. I found it interesting from a technical perspective and also he has a great taste in music. All going well I think it would be possible to get about 20m flying time out of it. The Xpeng is a working version of what he is trying to build.
Batteries are not really up to the job for mass market applications. These early versions are used for things like mountain rescue.

latest flying version and still not practical.. That has been around for years now. It's a petrol engine anyway. This is the way things are going.
You have 20 flying time. Something like this is already a useful gadget. 20m will creep up gradually, much in the same way as youtube was unusable at one time with low res and constantly loading videos.
Another 20% here:
Meanwhile, whilst waiting for batteries to improve the forward thinking people work on the rest of the design. You can always retrofit better batteries when they arrive.

It depends what you mean by 'gradually'. There is no 'Moore's Law' applicable here and so no rationale to expect the kind advances that made youtube videos run reliably within a decade |

There are too many idiots on the road already who seem incapable of driving sensibly on the ground. Giving them the ability to drive around in the air would likely prove calamitous,
Not a good idea even if a practical flying car could be produced.

There is no 'Moore's Law' applicable here and so no rationale to expect the kind advances that made youtube videos run reliably within a decade People say 1000Wh/kg would be good. We're at about 300 currently. As you move up the Wh/kg scale, you will find the number who find them useful will be much greater than a linear increase. An hour's flying time would make it very useable. As the man says, the cost is tiny compared to the cost of an hour in a helicopter. They are pretty quiet too. Noise make a difference, especially for leisure use. |

If they try and do anything stupid the computer can kick in and take over. all you need to do is get in and set the coordinates of where you want to go and the computer can do the rest. Even a baby could fly one. |

Noise make a difference, especially for leisure use. An hour is pretty poor (but triple the current). Helicopters typically have more than double this and yet this is considered one of their weaknesses So - if battery tech becomes more powerful by a factor of about 8 or 9 (lets call it an order of magnitude), then it will enable an electric flying vehicle with a similar performance to an IC helicopter |

Pure luxury. Naturally the Brits will be the last to catch on and will be harping at the Chinese for being too dangerous (eeek). Even 20m is OK for airport to hotel hops. |
