The whole idea of “mega” waterslides is a bad idea. Anything that goes that fast and has such a steep, long drop needs to be connected to rails so that it can’t fly up into the air. Waterslides need to be more gentle. I guess this is the tragic end result of making each ride more “extreme” to amp up the thrill.
Yes that is the problem - these water parks are outdoing one another to offer the most “extreme” rides.
