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 Ask what proportion of your journeys are over 100 miles, and if less, surely you would far prefer to climb into one of those and fly over all the chaos which is Blighty. 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. Well, 100 miles suggests a sped of 100 miles an hour, which is pretty optimistic. Let's be pessimistic instead and say it is closer to 50 miles (perhaps seventy). ..and then - you really do not want to be flying these things remotely near the edge of battery capabilities because a battery is a hairy and unpredictable uncle in a way that a full tank of fuel isn't. So 30 - 40? 20 miles better be okay , because you aren't going to get that much more than that without risking life and limb. The technology is awfully weak for various reasons |

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. 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. But you run into the same issue as driverless cars - insurance. When the computer fails and the thing crashes who is responsible - is it the passenger, the constructor of the car, the software developer, the guy who does the maintenance?.. Aviation insurance is a minefield in an industry that is heavily regulated and licenced - in something like this it makes the whole idea uneconomic. |

The technology is awfully weak for various reasons The 20m of the Xpeng is taking into account a safety margin. The speed depends on the type you have. You can do over 100mph but the way it is done is to have four wings. You take off like drone, then the wings rotate 90 degrees as it picks up forward motion. There is a prototype somewhere that does this. |

Aviation insurance is a minefield in an industry that is heavily regulated and licenced - in something like this it makes the whole idea uneconomic. The trick there is to use more than one computer. If it fails the manufacturer is responsible. Flying EVs have several safety advantages. They can fly on just two out of the four rotors, and each one is independent. electric motors hardly create any vibration which is a major cause of failure, and there are far fewer moving parts. Anyway, China recently introduced the laws necessary to set it up in China with designated airspace and regs. |

China has very poor consumer protection laws - something that is not going to be replicated in the West. These things will fall out of the sky and when that happens someone will be responsible.

British EVs will never fly though. They will have the world's best consumer laws but won't have any products of their own for sale. Most EV jobs will be writing complaints about them in the press. |

Pussies are quite smart. These are children in adult bodies who turn back to babies when they read the Daily Mail.
Here is an adult though in a grown-up world.
I think he went to be educated in one of those Confucius Schools.

And he is kinda wealthy at $280bn. How about you? |

And he is kinda wealthy at $280bn. How about you? I'm wealthy enough.
Actually he is the richest man in the world. He was the first man to run a business in China without the need to partner with a Chinese firm. He got special treatment from those on high.
I think it is because they like him. He never gave them any gip about human rights. He's into technology, so I guess they felt like he was into the same kind of stuff they were. It's how it works over there. You have to be a diplomat, not a child, as in the first video. The Chinese would see those as clowns.
In China if they think you are a clown they send you a clown smiley in their social media posts. Many British politicians have been in receipt of many clown smileys! They communicate in icons. If they like you, then you get a heart smiley. Send them a heart smiley and a China flag smiley and it would make their day. Most Chinese words are the combination of two simpler words, e.g. a dolphin is a sea pig.

Actually, he has wealth in a number of countries, one of those being China. And, yet again, I remind you that you need to visit China to see what it is realty like in real life. |

But you're the one dreaming of flying cars, which is an impractical and pointless techonology that only seems cool. The only development from the concept was to show off. The filthy rich in China can use private helicopters or jets and be received at the other end by their bullet proof heavy cars. |

The filthy rich in China can use private helicopters or jets and be received at the other end by their bullet proof heavy cars. OK well put it this way. What do the Brits program computers to do. I'll go through a brief list. Most of it is websites. If it is not some website it is usually a government computer like the Horizon system, and stuff so the police can track dodgy comments on social media and tons of stuff to run council bureaucracy. If it is not that it will be military, which is also a department of government, but it can be private "defence" firms too. as for the rest, well the only industry that i can think of except for set top boxes is computer games so the children can learn how to kill people, often by shooting them.
Over in China computers can be used for the above, but it goes far further. They run the trains over there. No need to pay 70 grand for a train driver when a computer can get it to arrive in the station to the exact second 24 hrs a day without crashing either. They use computers for manufacturing, and computers to drive cars. Pretty soon they will be flying EVs as well. China is a world expert in AI.

We have had driverless trains in Londons dockland for years Baron...
The DLR has been operating driverless trains since it opened in 1987. The trains are automated and have no cabs, but there is a small driver's console behind a locked panel at each end of the train.

Some BR executive type was explaining you would never manage it on the London Underground because the system of tracks they have is fucked. It's so old and antiquated that automating it is out of the question and would cause more trouble than it solved. I think one reason was to do with the tunnels being too narrow if a train broke down. China on the other hand has built all this up from nothing in the last couple of decades. It went from virtually no trains to tracks all over China, even in the most remote northern regions. |
