London - The 1997 Pont d'Alma tragedy could have been avoided if Diana and Dodi had remembered to belt up.
That's the stark message to a defiant Prince William pictured driving his bride without appropriate restraints.
"Yeah, Kate really, really hates getting trussed up with belts," one post-nuptial reveller said today.
"Besides, a seatbelt would have cut straight into her miniscule boobs - maybe even inverted a nipple through force of constraint...."
Onlookers said a devil-may-care twinkle in William's post-prandial eyes spoke volumes during the short journey from Buckingham Palace to Clarence House.
And despite being witnessed by at least 10 traffic cops, one dozen rooftop sniper-watchers, the entire Buck House Special Branch detail and a host of minor security guys not one teensy rap on the wrist was forthcoming.
"Six points on yer driving licence, mate!" a black cab driver called out in passing.
"F**k orf, you prole!" was the reply.
