The "euthanasia roller coaster" was designed by Dr. Juliannas Ubonnas, who studied for the Department of Interaction Design at the Royal College of Art in London. He called this roller coaster "ideal euthanasia machine" and "elegant and happy human lethal coaster".
The roller coaster runs for three minutes. The initial two-minute roller coaster rushes to the highest point at a very fast speed, and the highest height reaches 487 meters. The first two minutes are enough for passengers to think about their decisions. When they reach a height of more than 480 meters from the ground, they are given time to adapt to the height. When the passengers reach the highest point, they can think about their decisions and choose whether to die or live. If you choose euthanasia, just press the button to confront death.
