Exactly. And sorry, but doing it because it makes people "feel" safer is just ridiculous. Are they just going to leave it there? For no real reason, they are ruining ride experiences. NOTHING is safer about this.
Disney actually angers me with this. If you want to add capacity, just do it. Don't play pretend safety with plexiglass. People will decide on their own if they are comfortable with it or not.
And if people actually think they are safer because there is some plastic in directly in front of their face but air is flowing directly above and around them, then I don't know what to say.
You aren't.
