Exactly, no one reads the damn things. I don't even know or care what they say, and I don't want to spend 20 minutes reading a sign. Somewhere buried in their are probably the height requirements, but since no one reads them (unless Johnny Cochran is available for hire) I've seen people start asking the ops about the requirements, as well as other basic things.
They are 100% ineffective. You probably need a magnifying glass to identify which ride it is. Seriously, is the name of the ride even on the sign??
