I think you're confusing rides, Flight of Passage (Avatar) to the best of my knowledge is not VR (maybe traditional 3D glasses), Rise is definitely not VR (not even 3D) and Mario Kart is AR with a headset overlaying graphics over physical sets. None of them are VR in the traditional sense of the word.

The biggest test of VR at theme parks in the US came with various Six Flags around the country strapping VR goggles (Samsung IIRC) on some of their coasters and drop towers. They're pretty widely regarded as failures. I got to try two of them and they definitely were not a plus to the ride experience, especially on a drop tower where the view from the top is half the fun.

They are immersive, not using glasses, but projected environments and some kind of movement device being ridden. Why not just call it more expensive VR without headgear at that point?
