Ian I think we need to throw a coin in your eye for you to understand! If you lost your sight at a theme park for the rest of your life, you'd expect something about the park's safety procedures to change, wouldn't you?
I think the metal detectors have something to do with guest safety in the queue lines too, not just when you eventually sit on the ride! Yes it's a pain not having your phone in the queue but I can see why they're doing it. Hopefully this means Dragon Challenge will duel once more!
