Except the actual "safety issues" on most of these rides has not changed at all. In fact, even the particular circumstances surrounding Stardust Racers' safety hasn't been made any clearer, nor have they really changed since it first opened, they're just now realizing, "Hey, maybe our ride can kill people." Why? We don't know. They apparently haven't figured that part out yet, or they just aren't saying. Regardless, what does changing the safety protocol on other, completely unrelated rides solve? Or for that matter, changing protocols on Stardust Racers that may have little to do with the actual problem? Nothing, that's what. It's all reactionary nonsense to make it look like they're being proactive.
If they were actually stupid enough to start enforcing such a blatantly discriminatory restriction, I wouldn't be filing a complaint, I'd be filing a class action lawsuit. And since you've decided to be so condescending about it, I won't be sharing any winnings with you.
Why is that a problem? Because it's complete overkill that solves nothing in particular? Why are we pretending that altering operations elsewhere is somehow the magic bullet for fixing what happened on Stardust Racers, when it's so clearly not? Not to minimize the tragedy, but this is like chopping your hand off at the wrist because you burnt your finger... on your other hand. And just because Universal is a massive corporation that doesn't mean every business decision they make is a sound one (I can give you a whole list of very unsound decisions they've made over the years.) It's also not "standard practice."
