As someone who sees it all the bliddy time I personally think there is something sociopathic about people who seem to think that the rules do not apply to them and that they feel the need to have control and indeed power over a situation as petty as a seatbelt!
Just like the moron I witnessed going through security in T1 a few hours ago... he refused to tear his Blackberry from his ear for a minute (or indeed wait and finish his call) in order to pass through the metal detector. When confronted by the security scanner people on the other side (who for a change where actually very well mannered and indeed friendly and helpful to everyone else from what I could see) he then started doing that really stupid and pathetic "Im an important person" counter arguement thing where he tried to poke holes at every explanation given to him. In the end however he was just hauled off by the Mets finest! I doubt his office will be too happy with him when they find out!
