The sign says "Speed Limit 55," but I always go 65 and don't get a ticket. I don't find that confusing, though...

Life is full of rules that are only enforced some of the time. Seeing rules enforced against Bob but not against Sally really shouldn't be that confusing.

The UA photo rule is very strict, but is almost never enforced. What happened to MatthewLAX is very unfortunate, but ultimately not that typical.
