Open the drivers-side door HAL

Mass adoption of autonomous / self-driving cars will not happen in western society. BOOM! There I said it.

Now, this is just a prediction based on personal opinions about human nature / psychology, culture, law and attitudes. There’s no hard evidence behind it and I’m not pointing to a graph and trying to explain why these particular values mean Autonomous Vehicles (AVs) contravene the basic laws of physics dammit!

This is more about the technology succumbing to a confluence of sociopolitical impediments rather than having one single fatal flaw, or because of some technological impossibility. Also, I’m not for a moment suggesting that limited adoption of AVs won’t happen (it already has). Expect the Planned City in China that only has AVs, or the Palo Alto gated community with a fleet of corporate-sponsored AVs. I could also envision AVs being more widespread in a world without mass personal car ownership… but by that stage we’re no longer talking about the same “western society” that I see through my window every day.

The thing that fascinates me most though… is that we suddenly have a classic philosophical thought experiment (The Trolley Problem) bursting out of the realm of the hypothetical and getting right up in the faces of engineers. As someone who has been both an engineer and a philosopher, this makes me grin.

For those unfamiliar with the Trolley problem; you can go and read all about its history as a thought experiment on wikipedia. I’m going to explain it here though — but specifically in terms of how it relates to AVs.

So I got to imagining the guy working at the lab developing the Morality Chip. I bet they don’t call it that of course… that would really put the willies up Joseph Q. Public. But that’s what it is (yes yes, it’s actually software not “a chip”… but for dramatic purposes and ease of visualisation I’m imagining it as a discrete hard-coded “Morality Core” in every AI-enabled machine… an Asimovian safeguard against hacking). And whoever is working on that thing is spending their days asking some really weird questions… many of which centre on how many pedestrians your life is worth. Oh man, I’d love to be programming that thing. What strange afternoons they must be.

Clearly AVs will be programmed to take some sort of limited evasive action if they detect an imminent collision. And as soon as that evasive action involves more than slamming on the brakes (and even then, there are hypotheticals involving the relative speeds of the cars behind you); as soon as it involves altering direction as an emergency maneuver… we have entered a very weird moral universe.

It’s weird partly because it’s only inhabited by AIs.

OK. Maybe Formula 1 drivers. Maybe. But mostly AIs.

Here’s the scenario… you or I are driving along at a safe 50kph in a 60kph zone. Without warning, the truck in the oncoming lane (which is travelling too fast to begin with) has a tyre failure and suddenly barrels right towards us.

At that moment, you or I react based on a tiny number of urgent bits of information. Raw survival instinct, sheer panic and the most godalmighty injection of adrenalin instruct our arms to jerk the wheel towards whatever seems like the safest direction for us (and our passengers) at that moment.

Perhaps the pedestrian we kill continues to haunt our conscience forever. Perhaps their family hates and blames us. But if so, it’ll be completely irrational. The expectation that any human being has moral agency in that overwhelming fraction of a second; that terrifying moment during which their life has suddenly come under threat; a situation about which they possess incomplete information and literally not enough time to rationally consider options. Whatever emotions may swirl around afterwards, the law would not hold us accountable. And no rational person would.

But that all changes when the decision to swerve into the pedestrian is taken by a processor quick enough to actually weigh up the options. We inject morality into the moment. A situation that was previously just the chaotic outcome of uncontrolled physics and neurochemistry turns into The Trolley Problem. But no longer as a thought-experiment. Now it’s a design decision. And different people… different numbers of people are really going to die based on how our engineers are coping with The Trolley Problem.

The AV doesn’t jerk the wheel and mount the pavement out of sheer panic… it notes the trajectory of the truck, notes its own trajectory and it calculates that killing the pedestrian is the only guaranteed way to prevent a collision. Once it’s made that calculation… what do we — sitting in a quiet lab as the clock slowly ticks towards lunch — what do we tell the car to do?

Add some sauce to the dish… the car is self-aware enough to know how many occupants it has.

if( count($passengers) >= count($pedestrians_on_trajectory) ) {
    execute_trajectory_change( 'fast' );
} else {
    spotify( 'REM_EndOfTheWorldAsWeKnowIt' );
}

Will we see industry standardisation? Or will Mercedes place a higher value on driver life than BMW? Will that become a selling point? Will we have social oneupmanship, with some looking down their noses at people in non-Pedestrian Parity Approved brands? Will the cycling lobby demand a 1.1x multiplier to compensate for the additional speed above walking pace they are travelling? Strange afternoons.

Ford Motors
Guaranteed to value your life at the Texas legal maximum of 2.3 pedestrians!

With different implementations of the same technology there’s simply no way to know whether AVs from different developers are making the same decisions… whether they place the same relative values on human lives. But unlike that split-second monkey-brain decision we make under the most severe pressure we’re ever likely to encounter; this is very definitely a moral question. Deliberate decisions are being made. Imagine the scandal when they unearth the subfunction…

if( in_array( $passenger_nationality, 'french' ) {
    $num_passengers = $num_passengers - 1;
}


PS: I’m not suggesting that The Trolley Problem is going to sink AVs. As I say; the problem with this technology is more about — what I perceive as — a large number of different legal, moral, cultural and technological obstacles which are likely to combine to prove insurmountable in practice. This is just one of them. That said, the look on the face of the first guy whose car drives him off a cliff rather than hitting a couple of kids… the look on his face when his car actively prevents his monkey-brain-driven attempts to save himself… if that guy is me, I hope I have the last-minute presence of mind to glance in the mirror and take solace in how funny it all is.

PPS: Needless to say; this is all a very simplified stating of the problem facing the engineers. Once you throw in probability? Oh man, then you enter a world of weirdness. If “Evasive Maneuver 1” has a 40% chance of avoiding impact with the truck but is 70% likely to kill 2 pedestrians, does “Evasive Maneuver 2″ trump it? Despite being 99% certain to kill at least 1 pedestrian it has a 75% chance of avoiding a collision…”

Against High Speed Rail

Over in the UK the government has just thrown their weight behind a High Speed Rail (HSR) project to connect London and Birmingham. The project is backed not only by the Tory government (including their sycophantic whipping-boys the Liberal Democrats) but also by the opposition Labour Party. Indeed, with the exception of a few rebellious members of the main parties (mostly from constituencies through which the new rail line will run, but who don’t get any obvious benefits because trains won’t actually stop there) along with parties on the fringe, this HSR project has universal political support.

High Speed Rail (HS2)This contrasts with the striking lack of support from people living in those aforementioned constituencies which will be negatively impacted (some in reality, some perhaps just in perception) by the scheme. Homes will be torn down, the countryside will be cut through (despite parts of the route going underground, there will still be plenty of trees felled and habitats destroyed – 160 important wildlife sites according to unnamed “wildlife groups” in the BBC report) and idyllic rural villages will find their peace and quiet periodically shattered by the thunderous whoosh of a high speed train passing through.

The government, as has become de rigeur with these kinds of project, held a “public consultation” on the matter. These public consultations are one of the most annoying developments in modern political theatre. Basically the government of the day makes a decision, asks the people affected by the decision to agree with it – in the hope of sharing the responsibility if something goes wrong – and then completely ignores the results of the consultation if it turns out that people don’t agree with the decision. It’s the sort of craven and cowardly strategy that shouldn’t surprise anyone, given how craven and cowardly our political classes have become, but still manages to frustrate and annoy because of the magnanimous manner in which these consultations are generally announced. “Why yes, we will let you little people have your say on this matter… just don’t expect us to actually listen.”

In the case of the London to Birmingham HSR project (known as ‘HS2’; ‘HS1’ being the Channel Tunnel link) almost 90% of the 55,000 responses to the public consultation objected to it. Whether you agree with the project or not, this surely demonstrates that the actual consultation was a waste of time and money carried out in the vain hope it would provide positive PR. It makes no sense whatsoever for there to be a legal requirement to hold a public consultation unless there is also a legal requirement to actually listen to the results.

Of course, just because a majority of people along the route of a rail line object to it, does not itself make the project A Bad Thing. The concerns of those directly affected by any infrastructure project must be factored into the decision making process. But they should not – necessarily – over-ride all other factors. Major projects like HS2 have an impact far beyond the route itself. They provide economic benefits that radiate out from the project for quite a distance. And they may offer environmental benefits should the trains reduce the use of more damaging transportation. So it may often be the case – as with wind farms, for instance – that the objections of local residents must unfortunately be over-ruled in the knowledge that the wider benefits to society outweigh those objections. The impact on local residents should be minimised as far as is practical, and compensation should be offered where necessary.

The Question

So the question becomes: Does HS2 provide sufficient benefits to outweigh the negative impact on those directly affected and upon the countryside through which the line will run? Over on twitter, John Band made his position pretty clear when he wrote: “I think HS2 has now officially joined bendy buses on my List Of Transport Things Where It’s Fair To Assume An Opponent Is A Dick.” Now, I like John. Even if he is calling me a dick.

Because, frankly, I think the HS2 project is a ridiculous and damaging waste of resources.

Don’t get me wrong, investing UK£33 billion (almost €40 billion) in rail infrastructure is a bloody marvellous idea [UPDATE: As John points out in the comments, the 33bn covers the entire HSR network rather than just the London-Birmingham line, though this doesn’t affect my basic position]. It’s exactly the kind of thing that governments should be doing right now (and it’s a crying shame that our government here in Ireland is pouring money into zombie banks; money that could be upgrading our public transport network… or building hospitals… or employing teachers… hell, spend the billions on beer and pies if you must, it would still be a better use of the cash than pouring it into Anglo-Irish Bank). But investing money in the rail network is not necessarily synonymous with spending a massive lump-sum on a vanity project.

And that’s what it is. A vanity project. Railways are a great idea. High Speed Rail is a terrible one. A recent US study (High Speed Rail and Greenhouse Gas Emissions in the U.S.*) of the carbon emissions of various modes of transport suggests that travelling on HSR produces 20% more emissions than going by conventional rail, and almost double that of coaches. And that’s without factoring in the environmental costs of the actual infrastructure (which are high thanks to the large amounts of concrete and steel used).

And it’s not as if it’s providing a massive time saving either. HS2 won’t be teleportation. It’ll be more expensive than conventional rail and will reduce journey times by a shade over 40%. So the average saving between London and Birmingham will be roughly half an hour. Are the Tories really spending a fortune to cut up the countryside, screw up the lives of local residents and increase the cost of train travel, all to save a half hour? With WiFi available on UK intercity trains these days, it’s not like it even needs to be a half-hour “away from the office” for a lot of people.

Yes, from an emissions standpoint HSR beats cars and planes – by a considerable margin it should be said – but it’s really not in competition with them. Most people who make the journey by car are unlikely to switch to train without a major incentive. That incentive is on the way, of course, in the form of peak oil. But because HSR carries far less passengers than conventional rail, it makes much more sense to absorb any large switch from car to train using conventional rail [UPDATE: In the comments John points out that this is not the case… which invalidates one of my objections to HSR, though I still think that conventional rail – albeit on an upgraded system with a few billion invested in it – is far better than HSR in the face of Climate Change and resource depletion. So I still say that British rail investment should be going into upgrading the current rail network… increase platform lengths, buy some extra carriages and develop a new signalling system].

In fact, it makes even more sense to absorb the migration from private car into a new, integrated coach network. You want to travel from London to Birmingham? Simple. Build a large new coach station in Brent Cross, North London (i.e. within sight of the M1 on-ramp). Link it directly to the tube either via the Northern Line or the Jubilee Line (it would require a new branch of no more than a few hundred metres in either case). Then dedicate an entire lane of the M1 to express-coach traffic only. This will reduce journey times for coaches while providing an additional incentive for drivers to ditch their cars.

Yes, yes, Jeremy Clarkson and the rest of the motoring lobby will hate the idea… but frankly they will become increasingly irrelevant as oil price rises start to make private car use a luxury – long before HS2 is due to start running in 2026. Motorways will be half-empty by that stage anyway. No, an integrated coach network may not as sexy as HSR, but it makes a damn sight more sense environmentally, is a fraction of the cost to set up, makes use of existing infrastructure that will soon be significantly under-employed and will cost far less for the end user.

So… by objecting to HS2 I’m objecting to a massive infrastructure project that will damage the environment, will cost a lot more than it needs to, will be a dreadfully inefficient use of resources, will inconvenience more people than is necessary and will be more expensive to the end-user than the alternatives. If that makes me “a dick”, then so be it. Better that than flush money down the toilet and screw up the planet because I like shiny things that go fast. Which I do, but I’m not so idiotic as to want to base public policy on that fact.

* Although the study is titled High Speed Rail and Greenhouse Gas Emissions in the U.S., they actually looked at a variety of projects around the world and based their calculations on the emissions produced by the Danish IC-3 system, which they felt were representative of HSR as a whole.

April in Novi Sad

By pretty much any standard, I’m well-travelled. I’ve lived or worked on every continent bar Australia and Antarctica. But I’m not sure I’ve ever been anywhere that’s as filled with contradictions as Serbia. Mostly it reminds me of Greece in the early 1980s… despite not having a coast on the sea, the culture is primarily Mediterranean. The weather, the food, the pace of life, many of the more obvious mannerisms and attitudes. All very Med.

But on top of that are layers of difference. Contradictory as well as complementary. Certainly here in the north of the country, there’s a very definite central / northern European influence. Austro-Hungarian influences are everywhere. The architecture (leastways the pre-war stuff) and a certain “clipped” tone to the accent (though I’m told the south of the country doesn’t share this) means you never forget your proximity to Budapest and Vienna. And this Northern influence sits uneasily with the Mediterranean attitudes.

Though it’s often obscured by the other major influence on Serbian culture — the Eastern. The Slavonic. At the heart of Yugoslavia for two generations, the post-war culture was dominated by Russia. Never entirely within the Soviet sphere of influence (the Iron Curtain became more of a net curtain when it extended southwards towards the Med), Tito tried to walk a fine line between East and West. And in a sense he succeeded.

Obviously that’s a pretty damn controversial view, made all the more difficult to accept in the context of what happened to the region upon his death. Nonetheless, I shall expand upon this view when I return home next week.

For now, I have places to be and people to see. One of the purposes of this trip is to visit with the family of the lovely Citizen S. And the schedule is pretty tight. So until next time…

April in London (David Byrne gig review)

hallo y’all.

I’m sat here at one of those fancy web-terminals they have in public spaces these days. I’ve been in London for the past few days and am now on my way back to Dublin.

It’s been a groovy weekend and no mistake. London has changed in the three years since I left of course, but not by much. I felt utterly at home walking around the streets of Wood Green earlier today. Some of the shops are new, but most aren’t. There was familiarity everywhere I turned. The faces and voices. The smells. The shape of the buildings. The steel grey sky of London in Springtime. And that tree on Waldeck Road still has flecks of white paint on it. 16 years on! (about three people will know what that means, but they’ll get a smile from it. The rest of you will just have to wonder.)

The less said about The Queen’s Head at Turnpike Lane though, the better… London’s finest dirty rock pub turned into a sports bar? We live in profane times.

Anyhoo, I was over in London for a David Byrne weekend. Leastways, that was the excuse. Needless to say, the Byrnester didn’t disappoint. Though even if he had, the opportunity to catch up with some old friends was itself more than enough to make the trip worthwhile. I stayed with my old mate Gyrus (once again dude, many thanks for organising everything) and together we chilled out with a few cups of tea as well as attending a David Byrne movie double-bill at the BFI (Stop Making Sense and True Stories) on the night before the gig at the Festival Hall.

And what a gig!

I’ve seen Byrne at least once (and usually more often) on every tour since the eponymous album in the mid-90s. I’ve also seen several one-off shows (festivals and what have you). I can safely say he was never better than last night’s gig.

In fact, I’d kind of felt a bit worried about seeing Stop Making Sense on the big screen the night before the gig. Clearly live music and cinema are radically different experiences… but even so… how could his 2009 tour possibly match up to the performance on what is arguably the finest concert film ever made?

I needn’t have worried. The two can’t really be compared of course, but last night’s gig was simply breath-taking. As you may (or may not) know, the tour is called “The Songs of Brian Eno and David Byrne” and covers tracks from all of their work together… the two direct collaborations (My Life in The Bush of Ghosts and last year’s Everything That Happens Will Happen Today), the three Talking Heads albums that Eno produced (More Songs About Buildings And Food, Fear of Music and Remain in Light) as well as The Catherine Wheel (the Byrne solo album that includes a few Byrne-Eno compositions).

Anyways, it’s probably safe to say that while I’m a fan of pretty much everything Byrne has done; from ’77 to ’09; it’s his work with Eno that excites me the most. Well, Remain in Light is the best album ever recorded after all*.

I was delighted, so, when it turned out that the two albums that dominated the set were the latest one (naturally) and Remain in Light. He must have played at least half of that record. Needless to say, I’m hoarse from cheering.

Dressed all in white, the band and the three dancers (whose whirling, creatively slapdash choreography was at times funny, at times sexy and at times just weird, though always successful in transmitting energy to the proceedings) rarely stopped moving for the two hours. It was truly joyous, and how many gigs manage to even get close to that?

By the halfway point, everyone in the festie hall was on their feet. The audience reaction was incredible. The whoops, cheers and wild applause were heartfelt and real. Those in the lower tiers crowded down to the front of the stage, and the festival hall became a dance hall.

Life During Wartime, a glorious version of Once in a Lifetime (a song that has perhaps suffered a little from over-exposure but managed to sound fresh and wonderful all over again last night) and stunning versions of Houses in Motion and The Great Curve (“The world moves on a woman’s hips / the world moves when she swivels and bops”). Those were the highlights for me up until the encore.

Returning to the stage, still in white, but now with the addition of ballerina’s tutus, Byrne and the band launched into a blistering version of Burning Down The House. By the end, pretty much the entire hall was shouting the refrain… must have been a little bit like what Funkadelic gigs were like in the late 70s.

That wasn’t the end… but how to top that? Well, how about getting Brian Eno on stage for the final encore to provide backing vocals on the achingly beautiful title track from the last album? It was the cherry atop an already perfect cake. When the house-lights came up at the end, the Japanese chap sitting next to me asked in broken English… “the man at the end? He was Brian Eno, yes?” “Yes”, I said. He looked utterly delighted. It was the cherry for him too.

So yeah, that’s where I’m at. I must away now… my time on this terminal is running out, and I need to think about making tracks soon. If you get a chance to see Byrne on this tour, then you really need to. It’s bloody incredible.

* Excepting on the days when Astral Weeks is.
