I rode this. It was a little more alarming than I thought it would be, mostly because I was very conscious of how I was about nine stories above pavement, and how I was held in place with a little metal pin.
I pretended I was skydiving, which helped a little.
The centripetal force pulled my feet sideways, which didn't help.
Every so often, the ride made a sideways shiver motion, which was disconcerting.
