If the pic in #29 is the ride, then they can classify it any way they want. That’s not what I call a rollercoaster, and that’s not what I expect to ride when I’m looking for a rollercoaster.
I wouldn’t call it a roller coaster either but I also wouldn’t cynically correct someone who did.
That's a similar ride that has been redesigned to be safer. The ride that severed the teen's feet looked like this one. Notice the long exposed cable that runs the full length of the ride on the right hand side that is supported only at the top and bottom.
#29 is a picture of the ride in Arlington, Texas - at Six Flags Over Texas. As I recall, the article stated that this particular ride is of different design than the ones that have been shut down.
