Help needed - bike impounded by police

I think someone posted the guidelines for pavement fines.
If no one is being endangered and no risks are being taken a fine should not be given.
This is from memory so could be utter bullshit
IIRC, there was a statement to this effect when the legislation was initially passed, which has been much quoted on here. Unfortunately, this requires the application of common sense, which PCSOs (who were mostly traffic wardens until The War On Abstract Nouns kicked off, lest we forget) are famously free of.
