Car fare? (5)

I believe the answer is:

rolls

I'm a little stuck... Click here to teach me more about this clue!

'car' is the definition.
(short for Rolls Royce)

I cannot understand how the remainder of the clue works.

(Other definitions for rolls that I've seen before include "Baps - nice car" , "Bread portions" , "Car - goes with swaying motion" , "Moves by turning" , "breakfast food" .)

I've seen this clue in the Evening Standard.
