Compulsive motoring (7)
I believe the answer is:
driving
I believe this clue is a double definition.
'compulsive' is the first definition.
(thesaurus)
'motoring' is the second definition.
('drive' can be a synonym of 'motor')
(Other definitions for driving that I've seen before include "Behind the wheel" , "Hitting a golf ball off a tee" , "Controlling; motoring" , "Motorist's activity" , "activity on the golf course" .)
