I read that it would give the riders time to think things over, in case they realized they didn't want to die. The coaster would allow for those who change their mind to get off and descend once reaching the top of the hill, I think there was supposed to be a button riders could hit to signal the operator.

Huh. Never thought about it that way..

But. They have to get up somehow. So even if it was an elevator or escalator, it would still be their final ascension and potentially nerve wracking.

Can only think one way out of this... Maybe if the participant was anesthesia'd. Then one is suddenly awakened on top of this rollercoaster of doom, slowly watching the end come near. Each loop, closer to death. (That's how I feel most days 🙃)

Internet is strange place

Wikipedia rabbit holes are a hell of a drug.

The™ best™ question™, and applicable to pretty much all topics, too!

maybe it'd be better modeled by a 3d spiral? I'll hit up Desmos if I remember my polar coordinates right.

Ah my bad, I did not see the comment had a picture attached. There's probably a mathematical way to derive the shape of the euthanasia coaster as well, but I don't know.
