The "trolley problem" sets up a quandary: whether to let a trolley stay the course and hit numerous people, or redirect it and hit just one person. Recently, researchers have designed similar thought experiments around AVs.

Why it matters: AVs are being taught to drive safely and avoid harm entirely, just as human drivers are. But media coverage of these experiments, which assume unrealistic expectations for AV technology and suggest that AVs really could face such choices, may be contributing to public distrust in AVs.

What’s happening: In a recent MIT study, thousands of participants were asked whether an AV should kill a driver or a pedestrian, a homeless man or an executive, and so on, sorting people into categories as specific as male athlete, female doctor, small child, or baby in a stroller.

  • Participants' choices were assembled into a preference scale, ranking who is most preferable to spare or kill.
  • This study and earlier research have been widely publicized as capturing essential ethical insights that should be built into AVs.

The National Science Foundation, meanwhile, funded a group of philosophers working on computer modeling of how AVs could respond to different scenarios, depending on their ethical coding.

Between the lines:

  • There is no evidence that human drivers encounter instant decisions between two fatal outcomes with no alternative options. Programming AVs to anticipate such scenarios would not improve safety.
  • "Driverless dilemmas" mischaracterize AV capabilities. It's unlikely an AV could detect personal details, let alone a person's profession. Instead, AVs are being taught to track everything around them, and swerve or slow down to avoid hitting anyone.
  • Publicity of this research could be contributing to public distrust of AVs. It suggests that AVs will be unrealistically influenced by the ethics of their developers.

Yes, but: While AVs are not likely to face forced-choice ethical dilemmas, they may be taught to prioritize detecting and avoiding vulnerable road users, like pedestrians, over stationary objects, like parked cars.

  • In that sense, ethical choices would factor into programming, but in a context that aligns with how people are taught to drive in order to avoid harm.

IEA analysis charts "narrow" pathway to Paris climate goal

The pathway for transforming global energy systems to reach net-zero emissions by 2050 is "narrow but still achievable" and demands unprecedented acceleration away from fossil fuels, an International Energy Agency report published Tuesday concludes.

Why it matters: It provides detailed analysis and estimates of what's needed for a good shot at limiting temperature rise to 1.5°C above preindustrial levels — the Paris Agreement benchmark for avoiding some of the most damaging effects of climate change.

Tropical Cyclone Tauktae killed at least 16 people in India after making landfall in Gujarat Monday, packing 100mph winds, and sweeping across Kerala, Karnataka, Goa and Maharashtra, per Reuters.

The big picture: The storm unleashed heavy rains and winds as authorities continued to grapple with surging infection rates and deaths from COVID-19. Over 200,000 people were evacuated from Gujarat, and ports, airports and vaccination centers shut in the state and Mumbai, Reuters reports. Tauktae weakened from a Category 3 storm into a "severe cyclonic storm" Tuesday morning local time.

Scoop: Yellen wants business to help foot infrastructure bill

Treasury Secretary Janet Yellen is heading into the belly of the beast Tuesday and asking the business community to support President Biden's $2.3 trillion infrastructure plan during a speech to the U.S. Chamber of Commerce.

Why it matters: By trying to persuade a skeptical and targeted audience, Yellen is signaling the president’s commitment to raising corporate taxes to pay for his plan. Republican senators, critical to a potential bipartisan deal, oppose any corporate tax increase.
