Yeah, I actually thought that the phrasing of the blurb weighted the answers in a particular direction, and was surprised to discover that most did not answer questions about emergency vehicles as violating the rule. To quote specifically, it says "...please answer the question of whether the rule is violated (not whether the violation should be allowed)."

In fact, it sort of seems like this sentence should wreck the effort to demonstrate the difficulty of content moderation. I would think that a significant amount of the difficulty comes from instances where moderators feel that interactions between different rules mean they should allow violations of particular rules in certain situations.
