So why not let the user select the car’s “ethics setting”? The way this would work is one customer may set the car (which he paid for) to jealously value his life over all others; another user may prefer that the car values all lives the same and minimizes harm overall; yet another may want to minimize legal liability and costs for herself; and other settings are possible.

Plus, with an adjustable ethics dial set by the customer, the manufacturer presumably can’t be blamed for hard judgment calls, especially in no-win scenarios, right? In one survey, 44 percent of the respondents preferred to have a personalized ethics setting, while only 12 percent thought the manufacturer should predetermine the ethical standard. So why not give customers what they want?

So, an ethics setting is not a quick workaround to the difficult moral dilemma presented by robotic cars. Other possible solutions to consider include limiting manufacturer liability by law, similar to legal protections for vaccine makers, since immunizations are essential for a healthy society, too. Or if industry is unwilling or unable to develop ethics standards, regulatory agencies could step in to do the job—but industry should want to try first.

With robot cars, we’re trying to design for random events that previously had no design, and that takes us into surreal territory. Like Alice’s wonderland, we don’t know which way is up or down, right or wrong. But our technologies are powerful: they give us increasing omniscience and control to bring order to the chaos. When we introduce control to what used to be only instinctive or random—when we put God in the machine—we create new responsibility for ourselves to get it right.
