The Trolley Problem is a classic thought experiment in ethics, originally introduced by Philippa Foot in 1967 and later expanded by Judith Jarvis Thomson. It presents a moral choice: do nothing and allow a runaway trolley to kill five people on the main track, or pull a lever to divert it to a side track where it will kill only one person. In internet culture, the diagram became a versatile meme template used to illustrate difficult choices, absurd logic, or 'multi-track drifting' where both outcomes occur. It is widely used to parody corporate decisions, personal procrastination, and the inherent absurdity of utilitarian calculations in everyday life.
