I would dearly love to rip your whole post apart, maybe over a pint or two. I love folk that are at least capable of thinking about it. In your scenario, the machine is able to learn from its mistake. In my scenario, & the whole point of my post, is that the machine has just been destroyed because it caught a live grenade. The exception to the rule is that the machine can be taught to do anything . . . Except for an exception to those rules. If it truly has been programmed to learn from its mistakes then how can it possibly learn from a fatal mistake? True AI is a load of bollox & it will never happen. If you're buying... |

......
Fully autonomous vehicles can only exist if the possibility of "exception handling" is removed from the equation. Back when I was young & beautiful I gave a very famous lecture to a bunch of egg headed computer nerds many of which went on to create what is now the present state of technology. I invited a random member of the audience onto stage & we threw a tennis ball to each other. The math, the technology involved in having a robot play 'catch the ball' is phenomenal. Many people misunderstand just how difficult it would be to create such a robot, but it can be done. I'm trying to explain what is involved as we toss the ball back & forth. Then I substitute the ball for a hand grenade & confirm that the random member is OK with tossing a live grenade We tossed that grenade back & forth a few times before my finale . . . . Where I explain that given everything that is involved so far you can make a robot to accomplish this task. Then I pull the pin from the grenade, let the handle fly away to stage left, count to four & toss it. Have a good long think about what constitutes an exception to the rule, then have a good long think about sharing the road with a vehicle that cannot possibly ever comprehend one. First, exception handling is well established in computer programming - many programming languages provide a mechanism whereby unexpected events can be handled. Not necessarily complicated, in an autonomous car a good strategy for dealing with the unexpected would usually be 'STOP'. Secondly, if autonomous cars are forbidden by your logic then so are CNC machine tools because they cannot deal with exceptions like the operator falling under the cutter. Actually, with reasonable precautions, most of us are happy to take the risk. Thirdly, although humans are good at learning from experience, it can't be assumed people will deal with an exception better than a machine. Most fast human reactions are reflexes rather than considered actions; you cannot learn to drive by studying the Highway Code, you have to train your primitive brain to perform stops, gear changes, and steering etc. Our actions are at least semi-automatic. An extended childhood is necessary for this and we never stop learning. What doesn't kill us makes us stronger. However, the human process of learning by repetition can be emulated by a robot, or pre-programmed, and it may be good enough. Aircraft are capable of flying to a destination and landing without the pilot touching the controls. People rarely have to decide ethical questions when driving, but if a autonomous vehicle had to deal with a multi-choice exception it could apply the principle of least harm. It might get the answer wrong but so do people - all the time. A poor response is possible whenever taken by surprise by a novel situation such as someone throwing a grenade at you. Pretty dangerous whatever happens, maybe it's safer not to catch it, maybe the correct response is save others by altruistically falling on it. Attacking the thrower is also a valid response to your demonstration - don't try it at Heathrow unless you want to attract gunfire. There's a reason you weren't duffed up. It's because you didn't throw a live grenade. So there's no rule and no exception to the rule. It was a fake. The demonstration is faulty for another reason, even had it been a real grenade both machine and human are faced with a range of possibilities with no correct solution. There certainly isn't an answer that humans always get right and machines always get wrong. Airport guards are trained to shoot terrorists and a machine could be programmed to do the same. Both are capable of blundering into tragedy. Nice bit of theatre, but your trick proved nothing. I wonder how many of the egg head nerds were fooled? Dave PS counting to four with a real grenade would have given you a tricky exception to deal with. Most modern grenades explode two or three seconds after the lever is released. It's done to stop the other guy throwing it back. Grenades are designed to maim whatever the recipient does. |

![]() 23121 forum posts 1360 photos | For no particularly good reason, I will share a real event which happened this morning: Picture a set of traffic lights, with two clearly defined lanes on both approach and exit ... The exit lanes merge into one after a reasonably short distance [the implied rule being that the two lines of vehicles will take their places alternately]. As I approached the lights, there were two stationary vehicles [a car, followed by a van] in the nearside lane, and the outside lane was clear. ... so, I occupied the vacant position in the outside lane. The lights changed, and I held-back for a moment to let the car go first. I then realised that the van was tailgating the car and effectively [intentionally?] blocking my merge. My [necessarily split-second] decision was to pass both vehicles, to avoid the oncoming traffic. The manouvre was completed without undue fuss, but clearly irritated the car driver !! ... I would have liked to apologise and explain; but we rarely have that opportunity. So: What would the autonomous vehicle have done, in my situation ? . MichaelG. |

Whilst we are straying from the OP slightly I do think that it's still all interconnected. Complex problems require complex solutions. Will the AI that is capable of driving a car along a busy highway also be able to solve a marriage breakdown? Sounds silly doesn't it, but if you take a complex problem like driving along a busy highway & compare that to a complex problem like a marriage breakdown then anything that can miraculously solve 1 should easily be able to tackle the other. When AI can give coherent and unplagiarised A grade answers to essay questions on literary topics such as those I faced in A Level French: "Discuss Flaubert's use of symbolism and irony in Madame Bovary". "In Flaubert's Madame Bovary, how did Charles Bovary's personality persuade Emma to marry him and contribute to her downfall?" "In what ways is Madame Bovary a realistic novel?" then I will be prepared to change my present view: that there are significant limits to the ways in which AI can, and forseeably will be able to, substitute for or even merely help human beings. Perhaps, though, you were being ironic. |

2661 forum posts 294 photos | I think the last few posters are missing the point of computer AI. 2)AI developed for driving isn't designed for marriage counselling any more than your average HGV driver is trained for that role. It's likely that such counselling has it's own inherent rules, sympathies and persuasions that can be turned into algorithm's and if inserted into an autonomous HGV's database it could do both roles. AI improves with iterations (as do people with experience) 3) Madame Bovary. You went through several lessons at school being taught the sort of approach to analysing text and the sort of things examiners would be looking at to give marks. It had rules. Just consider the vast improvements that have occurred in voice recognition and translation software over the last decade. There has been software for a long time that can change a piece of prose into a particular authors style since authors have an (evolving) depth of vocabulary, individual understanding of grammar and punctuation, degree of verbosity, pretension etc. AI would at least have had a total memory of that book rather than limited human recall and a complete dictionary. |

Hi Michael You answered your own question. This would be my take on it, unless they are going to program in male aggression and selfishness. The cars would agree amongst themselves who would be first away from the lights. Cheers Michael |

I was trying to give an example for analysis and discussion; but evidently my first few words were the appropriate ones. MichaelG. Edited By Michael Gilligan on 14/07/2019 06:51:44 I've often wondered why they put that extra lane in. It serves two purposes, I suppose, that it shortens the length of queue at the lights and presumably was originally intended for ocassional heavy slow stuff to use nearside and allow nippy stuff to pass as the lights change. We've all experienced that two lane scenario coming up to a roundabout with an HGV on the inside and having to really keep a look-out that he has enough room for the curve of the roundabout without squeezing us... If that lane is really intended as a neat and polite alternate car feed-in then it has little benefit to an orderly queue and you'd think it'd be documented in the highway code (haven't looked). 1)You say if you'd braked someone may have hit you from behind. Yes I accept that in a real emergecy stop there may not be time to check mirrors - at least an autonomous vehicle keeps that info updated at all times - but also one hopes/expects that any driver behind you would be traffic aware and paying attention to your situation. If the vehicle behind was autonomous then it'd respond to your braking faster than a human reaction. 2)We have some variance on the possible reasons for that lane. I'm not so clear on why. 3)I wasn't trying to suggest you had anything to 'prove' as you put it but evidently your interpretation of queue rules was different to the van drivers and you felt you had right of way. 4) Apologies if I implied that you were aggressive but you may concede that the whole scenario occurred because primarily the van driver was being pushy while you interpreted the situation as your right of way. Such episodes are the usual initiator of road rage episodes even when it's a simple error by one driver. Hence we should all drive defensively. If id been in that situation then honestly it would be a case of what mood I was in - again something that wouldn't affect AI. If I was in my slow car with poor brakes then I'd have been driving carefully and cautiously. If i was in my EV with stunning acceleration and hot brakes and genuinely in a hurry or just feeling playful then i admit I might have floored it (my bad) but mostly I drive that with care 'cos it's so sodding expensive and repairs won't be cheap and age has slowed my reflexes - my excuse for buying a car that protects it's occupants that well. |

Questions: How do auto-piloted vehicles react to a good covering of snow? Do they simply stop? How about black ice? Can they see it? Do they attempt the impossible(like some drivers on u-tube videos where the vehicle simply accelerates backwards after losing adhesion attempting to drive up a slope? Perhaps they will simply take to the air in future? At the current level of autonomy of my car it will stay in self-steer if it can determine where the road is and it does that buy assessing edges and markings and making some limited assumptions. I have used self-drive in lousy rainy night conditions and monitored it's display when it's cameras were clearly seeing better than i could but in complelety covered road markings and snow drifts or confusing (to it) road markings or no road markings etc then at the present state of AI it won't self drive. How do you determine black ice? It's a combination of temperature, colour, reflectance and doubtless other factors AI will learn (really that means be taught by presenting it with multiple sets of data to sort out) what ators affect traction, cargo load and slope angle/camber. Your car at the moment has traction controls built in to assist. Elon Musk claims that the new Roadster will be available with a spaceX package option to give rocket thrust for acceleration and directional control and possibly short flight. He does make these wild promises and often they come to pass - somewhat later that everyone hoped. The limits of road car acceleration is down to tyre grip; rockets byass that. |

What the computer running a programme can NEVER do is to question itself whether it wants to play ball. Why not? What are the determinants? Social pressures, time of the month, work-load, sickness, muscle strain? I accept people and animals are hugely complex and the task to create an imitation of our behavious is huge - should one ever actually want to do it (rather pointless when people are cheap to make and easily thrown away) - then i dare say a simulation could be developed..... |

I was trying to give an example for analysis and discussion; but evidently my first few words were the appropriate ones. MichaelG. ... It's very useful to explore scenarios like this and score what humans do against the autonomous vehicle. In the example, I think autonomous has the advantage in this particular example:
Note that, apart from outright pilot error being number one, pilot error appears again in 'Pilot Error (Weather Related) and 'Pilot Error (Mechanical related) Here's one where a human might do better. You're driving at speed up an empty road where temporary traffic lights are protecting the movements of a digger just out-of-sight round the corner. The lights have failed. A human might spot the hazard by recognising the in-position lights are not Red, Green or Amber. He should slow down. As the car's map is wrong it has to rely on its sensors and might be travelling too fast to stop in time. But, as I noted earlier, once a hazard is detected, the car will react much faster than a human. We can rely on them to do super-human emergency stops. Maybe even in this situation human and car might score about the same. On the other hand, autonomous cars wouldn't deliberately or accidentally jump lights as most people do at one time or another. In my experience bad drivers are more common than broken traffic lights! At root I think autonomous cars are an engineering problem with engineering answers. It's not essential for drivers to be human. Dave |
