Drives back to see films about parking (6)
I believe the answer is:
repels
'drives back' is the definition.
('repel' can be a synonym of 'drive back')
'films about parking' is the wordplay.
'films' becomes 'reels' (reel is a kind of film).
'about' means one lot of letters goes inside another.
'parking' becomes 'p' (abbreviation on road signs).
'reels' enclosing 'p' is 'REPELS'.
'to see' acts as a link.
(Other definitions for repels that I've seen before include "Drives away from lepers" , "Drives back or disgusts (6)" , "Disgusts or drives away" , "Forces back" .)
