It's so far-fetched that it's intended to be a thought experiment rather than a role play, which I think people miss. The <i>entire point</i> is to factor out all those innumerable details which complicate every real-life situation to see if there are underlying principles that can be illuminated. It's not about whether it's a trolley switch or a gun or a baby-grinding machine, it's about if there's an answer to how many babies you're willing to grind up and for what.

But it’s reasonable to question the usefulness of any supposed insights gained from thinking through one’s answers to the trolley problem. It’s quite conceivable that no insights can be extended at all to any scenario in the real world.
