Dispense with parking for cars, perhaps (5)
I believe the answer is:
scrap
'dispense with' is the definition.
(thesaurus)
'parking for cars perhaps' is the wordplay.
'parking' becomes 'p' (**).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'perhaps' indicates anagramming the letters.
'cars' is an anagram of 'scra'.
'p' after 'scra' is 'SCRAP'.
(Other definitions for scrap that I've seen before include "Waste metal or slang fight" , "Small amount; fight" , "Cancel; fight" , "Just a fragment, maybe of food" , "Break up - fight" .)
