Agreed Fozzer, for those of you on the other side of The Pond who might doubt, or be complaining well think about this little piece of research my the British Motor Vehicle Safety chappies.
An average sized two year old in a car not wearing a belt in a head on collision at 30 mph has the same effect as a fully grown African bull elephant (something to do with physics!) when it hits the windscreen (or adult seated in-front of them).
My advice wear the belt, don't compain, and if the officer stops you, be polite and point out that you have enough brains to wear one! I'm sure the officer will be v.nice, I always found the CHiPs chappies v.polite, especially when they pulled my dad for speeding

PS. Kevin I would ALWAYS wear a lid and leathers, I was in Greece some 8 years ago and ended up in hospital with my head split open (windsurfing accident), and they brought in a German tourist who'd come off a moped wearing only shorts and flip-flops. I'm not squeamish, but I nearly puked. He died lying there on the bed next too me, there was just so much of his body missing, and he'd come off at about 20 mph. Most of his face was gone....

I could see his ribs (the skin flailed off his chest. The right arm and leg looked like bits of meet hyenas had been chewing on for a few hours. Convinced me of safety first!
