Extract

The advent of fully autonomous vehicles (AVs) raises many questions. While some appear purely technical, others engage matters of public policy, sometimes with a prominent ethical component. Our expertise lies in law and applied ethics, and so our inquiry will focus heavily on legal or ethical issues arising from a widespread adoption of AVs and their response in emergency situations involving animals. By “animals” we do not mean all other animals than humans. We will concentrate on interest-bearing animals. These are animals who possess a welfare or wellbeing, animals whose lives can fare well or badly from their perspective.

One of these is that in the trolley problem the choice must be made under the pressure of emergent circumstances, with no chance for deliberation. In contrast, in the AV situation the decision can be made in advance, and after wide consultation. A second difference is that in the trolley problem all the outcomes are distinctly specified in advance; they are known to the chooser. In the AV problem, there is uncertainty, incomplete information, and risk: swerving into the tree could possibly kill the AV’s occupants, but might only injure them. This last point is explored in Björn Meder et al, “How Should Autonomous Cars Drive? A Preference for Defaults in Moral Judgments Under Risk and Uncertainty” (2019) 39:2 Risk Analysis 205.

In the civil sphere it is more likely that the advent of AVs will cause more jurisdictions to adopt a no-fault regime for vehicle accidents. The operation of tort law in respect of personal injury and property damage caused by automobiles will be legislatively eliminated and replaced with a no-fault compensation scheme similar to that already in place in Quebec.

17. Jean-François Bonnefon, Azim Shariff & Iyad Rahwan, “The Social Dilemma of Autonomous Vehicles” (2016), 35 Science 1573 offers the results of an empirical study that shows that most people would like others to buy AVs that had a Utilitarian algorithmic morality, but themselves would prefer to acquire AVs that protect their occupants at all costs. Against that there is some empirical evidence that when whom-to-harm situations do arise on the road human drivers make decisions that seem informed by a Utilitarian outlook: Anja K Faulhaber et al, “Human Decisions in Moral Dilemmas are Largely Described by Utilitarianism: Virtual Car Driving Study Provides Guidelines for Autonomous Driving Vehicles” (2019) 25 Science & Engineering Ethics 399. None of the hypotheticals employed in this study involved nonhumans.

18. The title of a recent article suggests yet another variation: Derek Leben, “A Rawlsian Algorithm for Autonomous Vehicles” (2017) 19:2 Ethics & Information Technology 107. Driving behind a veil of ignorance strikes us as problematic. In an even lighter vein Adam Gopnik speculates about a Nietzschean version which would drive right over anything, and also software inspired by Albert Camus “which would stall and pause in the middle of the highway while the traffic backs up behind—and then suddenly shoot off, bang, because the existential leap must be made, and some pedal struck.” A Gopnik, “A Point of View: The Ethics of the Driverless Car” (2014), online at BBC News online https://www.bbc.com/news/magazine-25861214 [perma.cc/2H7F-DWFS].

19. Presumably police cars, fire engines and ambulances will have software that differs from that mandated for private vehicles—for example, by permitting breach of speed limits and some other traffic regulations.

20. We sidestep the question here of whether the legal response to this question will or should be imposed at the national level or provincially. That will depend on as-yet unresolved questions of constitutional law. Present laws governing vehicles in Canada exist at both the federal and provincial levels, and questions relating to the advent of AVs are being discussed at both levels. While a uniform national response seems simpler, provincial variation is possible. AVs equipped with GPS can tell when a provincial border has been crossed and adjust accordingly. Indeed, these will be necessary, since traffic laws already differ provincially—e.g., whether a right turn is permitted on a red light. So AVs’ software will already have to respond to legal differences arising from crossing provincial borders. That being so, there could be software that responds differently in a whom-to-harm situation depending on the law on that matter applicable in the place where the vehicle happens to be at the time.

21. The view that the software for whom-to-harm problems will not be left to individual manufacturers or AV owners is broadly accepted: Ivó Coca-Vila, “Self-Driving Cars in Dilemmatic Situations: An Approach Based on the Theory of Justification in Criminal Law” (2018) 12:1 Crim L & Philosophy 59 at 61-63; Jan Gogoll & Julian Müller, “Autonomous Cars: In Favour of a Mandatory Ethics Setting” (2017) 23:3 Science & Engineering Ethics 681; Belay, supra note 11 at 129.

22. We suspect that they swerve less frequently for animals than for humans. A study that asked American college students whether, as drivers, they would swerve to avoid killing a pedestrian, even at the risk of injury to themselves, elicited the following responses: 94% would swerve to avoid hitting a human child, 84% would swerve for an adult, and 27% for an (unspecified) animal: Katherine Brunk, “The Pedestrian Safety Problem and the Ethical Implications in the Age of Autonomous Vehicles” (2019), online at All Theses 3131, Clemson University https://tigerprints.clemson.edu/cgi/viewcontent.cgi?article=4138&context=all_theses [perma.cc/L4GB-6AJF] at 41-42.

25. Drivers can even be liable for property damage caused when they swerve to avoid killing a cat that runs in front of their car: Falkenham v Zwicker (1978), 32 NSR (2d) 199, 93 DLR (3d) 289 (SC).

26. Sutherland v Glasgow Corp, 1949 SLT 388 (2nd Div). There, the court was quite clear in articulating the choice as being between the life of the animal and mere minor injury to a human. Although the court found that the driver’s actions did save the dog’s life, it still held that he had made the wrong choice. He should have pursued the option that involved killing the dog but not bruising his human passenger. For a Canadian case where braking (not swerving) and coming to a stop to avoid killing a small animal was held to be negligent, see Gill v Bains, [1985] BCJ No 510, Vancouver Registry No B831070 (SC).

30. Something like this was the conclusion of the German Ethics Commission, supra note 10. Recommendation 7 states that AVs “must be programmed to accept damage to animals … if this means that personal injury [to humans] can be prevented.” One scholar who anticipated our fear that AVs might make things worse for nonhumans is Oliver Bendell. See Oliver Bendell, “Considerations About the Relationship between Animals and Machine Ethics” (2016) 31:1 AI & Society 103. But his reasoning (at 107) was that AVs aligned to economic interests would avoid swerving because they would prefer to damage animals rather than the car.

34. The Utilitarian RG Frey accepted both that we have direct duties to other animals and that some humans did not enjoy a higher moral status than some other animals. See RG Frey, “Animals and Their Medical Use” in Andrew I Cohen & Christopher Heath Wellman, eds, Contemporary Debates in Applied Ethics (Blackwell Publishing Ltd, 2005) 91.

35. It may seem odd to use Kant here, particularly as his view is quite a dated one. We have two reasons for our choice: (1) As noted above, Kant provides a clear and well-known indirect duty view of animals. (2) Unlike contemporaries like Carruthers (Peter Carruthers, The Animals Issue: Moral theory in practice (Cambridge University Press, 1992)), he also evidences some surprising sensitivities to other animals despite their lack of moral standing. Of course, Kant is also a giant in theoretical ethics and so, despite the fact that Kant is long dead, his influence continues unabated.

38. There is a risk of using the Lectures on Ethics as a source of Kant’s thought. These are not, on the whole, notes taken during his lectures. They also do not reflect his mature thought. (On this point see Alice Pinheiro Walla, Review of Kant’s Lectures on Ethics: A Critical Guide, Lara Denis & Oliver Sensen, eds, (2016), online at Notre Dame Philosophical Rev https://ndpr.nd.edu/news/kants-lectures-on-ethics-a-critical-guide [perma.cc/SEM6-3HSU]. Nevertheless, the position on our indirect obligations to animals, taken in those notes (and we will limit our use of primary sources for Kant’s view on animals to Lectures on Ethics), is useful for our discussion as they reflect a reasonable view taken from that vantage point.
