I ride like this, so I can't get smug or censorious, but the Police seem perfectly reasonable, polite and constructive in this clip.
Not sure how it is a stupid place to be earning revenue. If you see it as a revenue-generating exercise, you may need to reflect a little. The authorities could earn far more, far more quickly in other ways.
They are trying to make the highways safer - and in their view (and the view of the Law) your riding in that clip was doing the opposite.
You were very polite and took your medicine, but to then go online with the comment "Still a stupid place to be raising revenue" smacks of teenage sulk more than anything.
It reminds me of speeding drivers (I have a dreadful track record of SP30s and big fines) who bleat about revenue-generation when really they just chose to ignore big roadside signs and a needle on their dashboard that points at numbers.
I'm glad you put the footage up, as it shows the Police in a good light. But it is not a stupid place to stop lawbreakers.
