You'll have to be a bit more specific than that.

I fail to see why other road users, including
pedestrians, should have to suffer their bullish behavior because 'they'
choose to behave like louts once a month.

I fail to see why cyclists should put up with the bullish behaviour of
motorists on every other day of the month, but YMMV.

This requirement is a notice to all that public anarchy once a month will
no longer be tolerated. A notice which is long overdue in my opinion.

If you want to know the time, ask a policeman. But if you want advice
on a point of law ...
