I hear ya. I get what you're saying. But, you know, this IS a fan forum where internal workings are often discussed in great detail. One could argue its none of our business, as guests, to know how long the character sets are for the "friends" who facilitate all those meet-n-greets but its of interest so it'll get discussed.
I'm not personally asserting that this particular monorail tractor incident is a direct failure on Disney's behalf. It does kinda get me thinking what secondary systems these vehicles have, etc. mostly because its interesting and I like to know this stuff. It's the nerd in me.
The safety aspect for the workers also is of interest because I worked directly with these types of things and safety procedure is such a big part of my husband's work in refineries and other facilities. From that perspective I find even near misses, procedure, etc. interesting. Definitely worthy of harmless conversation.
