In 2011, designer Julian Urbonas proposed a project of American mountains for euthanasia. The wagon, according to his design, will move with such overloads that the human body will not withstand. The visitor of this “attraction” dies without torture, even experiencing euphoria. The project has a solid scientific basis - its consultant was Michael Gresti of the Laboratory of Spatial Desorientation at Imperial College London, studying the disorders of the vestibular apparatus and the problems of dizziness and dizziness in transport.
