Euthanasia Rollercoaster Designer Unveils 'Final Words' Feature

Lithuanian engineer Julijonas Urbonas designed a conceptual 'euthanasia rollercoaster' intended to kill its passengers through extreme G-forces. The ride, which features a series of increasingly tight loops, would subject riders to 10Gs of force, leading to cerebral hypoxia and eventual death. The design includes a protocol where all 24 passengers must press 'go' to proceed, allowing them to say their final words before the ride begins. The project, which won a technological art prize in 2013, remains a hypothetical exploration of euthanasia.
