>I don't understand the bright line you're drawing between "murder someone by pointing a runaway trolley that would otherwise absolutely miss them in their direction" and "murder someone by harvesting their organs." The difference is key to understanding policy decisions like this. You absolutely use math with lives when you're making policy. Right down to calculating lives with dollars. If there is a fixed budget of $100M to apply to saving people's lives, you ideally will divvy the money around in such a way that the most people live. You don't extend one person's life by 1 month using extreme measures that cost $50M and let a hundred die who would could have had their lives extended by years for $50k each. To some degree the original question is a real-world policy example of the trolley problem: Do we allow companies like Tesla to save thousands of lives, possibly your own, in exchange for indemnifying them against the (ideally) few lives lost (also potentially your own) when the technology fails? That sounds identical to the air bag policy: In both cases the life saved could be yours. You might not even get into an accident if there were enough self-driving cars, so not only would you live where you might have died, you might even avoid an inconvenience. I'm not talking about seeking out people and killing them. That is committing murder for an alleged "greater good", and the ends don't justify the means. I'm talking about redirecting a trolley that is going to kill five random people and instead making it kill only one random person. And we can talk about focusing on further advances to make sure that one person doesn't die (statistically speaking) either, but I think that throwing the switch, in a policy sense, is always the right first step. I think the moral argument that flipping the trolley switch is wrong is bankrupt, and that it does map onto the real world and real world policy decisions like requiring mandatory air bags. Flipping the switch isn't murder. Not flipping the switch when you have the opportunity is murder.
