'rod's' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'extremely responsible travelling north after parking fine' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'travelling north' shows that the letters should be reversed in order (in a down clue, letters go up).
'after' says to put letters next to each other.
'parking' becomes 'p' (abbreviation on road signs).
'fine' becomes 'OK' (synonyms).
'responsible' with its centre removed is 're'.
're' reversed gives 'er'.
'p'+'ok'='pok'
'er' after 'pok' is 'POKER'.
