One who gives talks about parking next to European driver (8)
I believe the answer is:
operator
'driver' is the definition.
(thesaurus)
'one who gives talks about parking next to european' is the wordplay.
'one who gives talks' becomes 'orator'.
'about' indicates putting letters inside.
'parking' becomes 'p'.
'next to' says to put letters next to each other.
'european' becomes 'e' (abbreviation e.g. EU).
'p'+'e'='pe'
'orator' going around 'pe' is 'OPERATOR'.
(Other definitions for operator that I've seen before include "Agent that runs some apparatus or machine" , "Speculator" , "Person running a business" , "User of machinery" , "Controller of machinery" .)
