Rubbish

I think we can safely say on the day of a Royal Wedding outside their own Palace, the Royal family can do whatever they damn well please.

I think they call it a "perk."

The roads had been closed off so I expect that normal rules did not apply

There are about ten xemptions to the requirement to wear seat belts, one of which is:

"A person riding in a vehicle whilst it is taking part in a procession organised by or on behalf of the Crown."

Also I think you'll find that it was to do with the ages of the vehicles concerned. Seat belts did not need to be fitted until a certain date (mid-70's springs to mind) and all the motors they used were well older than that. Ergo... if seat belts are not fitted, you can't be expected to wear what isn't there. Even in a modern car, one of the exceptions to the requirement to wear a belt is that the belt must be working properly, so you (or the car driver) might be prosecuted for the con & use offence of not working/not fitted belts, but the would be belt-user would not be prosecuted for not wearing it.

Hello, Ludwig, all cars made after April 1965 had to be fitted with seatbelts, but wearing one was not compulsory until 1983. However, most people had got into the habit by the end of the seventies.

While we're on the subject, I wonder what the fine would be in normal circumstances for driving a car with a non standard number plate on the back? Non-standard in the sense of a physically impossible registration (JU5T WED), different to the genuine one on the front and, no doubt, bereft of the requisite manufacturer's markings, BS number etc. If that isn't just the most flagrant attempt to avoid the Congestion charge, I don't know what is...

And for a non-learner to be showing an L plate, too. Outrageous!

Balloons and ribbons! I mean, if that isn't a blatant disregard for H & S regulations... The chance of a member of the public being alarmed by a popping balloon or being strangled by a stray ribbon....

Reminds me of a bumper sticker I once saw during the heady days of the Yuppie 90's -"Actually, I DO own the road!" 'Nuff said.

Happy Honeymoon !!
