Driving in the city, perhaps, with not entirely sophisticated car (5,4)

'driving in the city perhaps' is the definition.
(as in driving a golf ball)

'with not entirely sophisticated car' is the wordplay.
'with' says to put letters next to each other.
'not entirely' means to remove the last letter (not all of the word).
'sophisticated' becomes 'urbane' (similar in meaning).
'car' becomes 'golf' (I've seen this before).
'urbane' with its last letter removed is 'urban'.
'urban' put next to 'golf' is 'URBAN GOLF'.
