So successfully that parks have removed most of them by now. I don't think VR tech will be consistent or polished enough to be more than a novelty in coasters for quite some time. The light leak, motion sickness, overheating, and positioning issues are magnified several-fold outdoors on a coaster.
It's dynamic enough that you'd be able to re-theme the ride with minimal effort, something akin to what they want the Dreamworks theater to be. I'm imagining having a queue with similar set-pieces to MMRR where you can alter them through projection mapping and lighting, then the ride itself is entirely VR and can be changed out periodically.
