God made man run after motorists, collecting tax (6)
I believe the answer is:
avatar
'god made man' is the definition.
(avatar can mean a god in human form)
'run after motorists collecting tax' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'after' says to put letters next to each other.
'motorists' becomes 'AA' (Automobile Association).
'collecting' means one lot of letters goes inside another.
'tax' becomes 'vat' (UK Value Added Tax).
'aa' going around 'vat' is 'avata'.
'r' after 'avata' is 'AVATAR'.
(Other definitions for avatar that I've seen before include "Divine manifestation" , "Incarnation of a Hindu deity in human or animal form" , "High-grossing James Cameron science fiction film" , "Archetype" , "A person who seems to embody a particular ideal" .)
