Plane auto-pilots, chess, Monopoly, AI - there seems to be a lot of confusion over the challenges that autonomous vehicles face and their applicability to other problems. An AV doesn’t need to learn how to be a completely different vehicle, it doesn’t need to enjoy driving and it doesn’t need to dream about electric sheep when it is being charged.
I think possibly the biggest issue has been mentioned, though - the “theory of mind” element that is required in order for an AV to mix it on the road with other drivers. As has the ability to recognise and deal with ambiguous situations (where humans often apply “theory of mind” elements to muddle through, so that relates to the first issue).
It’s much easier to envisage AV’s working very well on AV-only roads where they can communicate with each other electronically, but that’s a whole messy infrastructure problem.

Whilst you’re quite right, the point I’m trying to make is that auto pilot exists to aid pilots, not replace them.

Also, aircraft pilots are monitoring everything very intensively while the plane is in flight, regardless of whether auto-pilot is engaged.
This is completely different to the intentions for self-driving vehicles.
Precisely and it’s auto pilot that enables them to do that. They wouldn’t have much time to monitor the instruments if they were busy pissing around with the yoke and pedals for fourteen hours.

There’s quite a big emphasis on monitoring and optimising fuel burn. Which, as a totally uninformed opinion strikes me as the kind of thing that you might expect computer algorithms to be a good fit for.
I’m sure an aviation enthusiast on here would easily be able to explain why that’s not correct, though.

Driving a car involves a non-limited set of circumstances - the challenge is to create an AI that can adapt to something it hasn't trained to deal with. But if it hasn't trained to deal with something, it has no general principles to fall back on. And it appears that some (many) AI developers refuse to recognise that this is even a problem.
Gary Marcus, who I referenced above, advocates a hybrid approach in which human-inputted principles are combined with the results of computer self-teaching. Even then, I'm not sure it will solve the problem.
Going back to chess to illustrate the point, at one stage in the development of chess computers, where the advantages of showing it past games to learn from were being discovered, a computer that had been shown a bunch of grandmaster games started inexplicably to throw its queen away at the first opportunity. Why? Because it had picked up on the fact that when a player sacrificed their queen in the games it had studied, that player usually won - grandmasters won't sacrifice a queen unless they're very confident that they will win in very short order by doing so. The computer eventually overcame this compulsion, but the fact it had so blindly done so at one stage in its learning was revealing. This relates to the point you made earlier about computers confidently making catastrophic mistakes. It didn't ask itself the question 'why?' It didn't think about why the queen was being sacrificed. That's because it doesn't really think at all.
There is a certain 'naive AI' approach, which appears to be common, that holds that self-teaching 'neural network'-type systems will arrive at things like 'understanding' as an emergent phenomenon that results from complexity. But it hasn't happened yet. No hints of it happening yet have appeared. I suspect that this is because understanding doesn't emerge as a result of complexity. Understanding emerges as a result of life processes. So Marcus's idea of welding general principles to the computers' self-learning may well help, but if the computer didn't come up with those principles itself, it won't actually understand them. They will be a sticking plaster at best.
I know pilots input fuel payloads into the systems of commercial jets so there must be computational requirements for it. My knowledge ends there though. I never got into the jets when simming.

These neural net type systems need to be many layers deep before they can even emulate the processes of a single neuron.
I agree that many of the ideas around the applicability of AI to problems like driving on a road that has human drivers on it are misguided.
If the problem is solved, though, I don’t think it will involve “hard AI”. I think it will be a case of dedicated machines that do nothing but drive and have very limited adaptation capabilities once they leave the assembly line.

I think another way of looking at it is that you can teach a car how to drive but you can’t teach it how to be a human. That’s means you can’t get it to anticipate a human doing things it hasn’t seen before, which is the very essence of being human. And that means the only way to make sure the car’s ability to drive is not compromised by a human doing something novel is to remove the humans. The result would be dystopian indeed — cities even more impenetrable to pedestrians than they already are and people shut out from systems unless they can afford access to the AI transportation.

Yep, pretty much my conclusion a few posts back. Though how dystopian it would be would come down to political and economic decisions.

Yeah, I agree that AI-only roads would be more feasible. Can't see that happening any time soon, although maybe somewhere like China might try it.
China already uses AI face recognition to prosecute people for road offences. Marcus in that podcast references a case where a famous Chinese actress received a court summons through the post. Turned out that her face had been on a billboard opposite where a road crime had taken place.
These things are nowhere near fit for purpose as yet. And those purposes themselves are really quite unsettling.

Now I think about it, this whole AI driving problem is neatly encapsulated by this image
Easy for a person, who understands the purpose of things like crosswalks. Apparently so difficult for a machine that it’s still the de facto way to act as a gatekeeper against machines.

Some pretty poor software testing going on there.

Would be interesting to know whether researchers are chucking advanced systems at this. It’s largely a security measure to stop entry from systems with no AI element at all.
Even reading the instructions for different kinds of test is quite a difficult computing problem.

Maybe, or maybe it is just inherent to these things that they'll do something really dumb eventually.
In this case, the computer failed the 'Father Dougal Test': 'This is small; that is far away.'

I think a lot of things get called AI that really aren’t, even taking into account the somewhat ropey definitions that get used.
Just being able to find a face and pass it to the recognition algorithm seems well below par, and something that you’d catch with reasonable testing.

If the woman's face just happened to be the size appropriate to someone in the car, perhaps as seen through the window on the other side of the road, the only way to pass the Father Dougal test is to have an understanding of the context in which you are seeing the face. That's not simple, at all.

I think that might have been hinted at.
And it looks like a reasonable proposal tbf, except for the lack of a trillion or so in venture capital.

One of us would be losing money as I strongly suspect that something like that did happen. Be surprised if the computer didn't have information about how big a face is from its training, but that on its own doesn't solve the Father Dougal problem.

UK's first self-driving bus takes to the road for tests in Scotland
Passengers are expected to start using the self-driving bus this summer as Scotland begins testing the "hugely exciting project".
Scotland will today start testing a new self-driving bus that is set to become the UK's first fully sized autonomous vehicle of its kind to take to the roads.
Stagecoach will be carrying out on-road testing of its self-driving bus from today in preparation for passengers stepping aboard later this summer.
The buses will be full of sensors that enable them to run on pre-selected roads without the safety driver having to intervene or take control.

It thinks it's playing noughts and crosses.
Facial recognition is something AI still terrible at, from not recognising dark-skinned people to confusing toys and anything vaguely face-shaped with humans. It is improving all the time, but I really don't think it'll ever be able to cope with the differences humans can cope with. I always pose the example of a small child dropping their teddy bear or doll, which lands with its face visible to the car, and the child turning back to pick up the toy, face away from the car. The car would swerve away from the toy because it sees a "human" face, and, if there's a car or another human on the other side, towards the child, because it doesn't see one there.
It's not a situation that would guarantee a human driver would never kill the child, but an AI would be actually aiming for them.

Weight is meaningless
A bit of context on "edge cases" and what the state of play is at the moment can be found here. The driver is a former worker on Tesla AI systems who got fired for making videos about how it was (and wasn't) coping with driving around San Francisco (xref that one with Elon "free speech" Musk eh). A couple of notes on this as well - San Francisco is, like most US cities, a relatively simple grid model with nice wide roads, a couple of oddities (tram lines) thrown in and a bit of construction work going on, being driven at a relatively quiet time of day. It's safe to say the system is nowhere near ready for primetime in European cities yet, let alone in a position where it should be exempted from crash liability.
And this is it absolutely failing - very dangerously - to deal with more winding mountain roads in a video uploaded yesterday.

A single seater autonomous pod. I can see this replacing taxi's but not helping with congestion. It looks far too small for a half decent shop even Gordon Murray Design
