One without a car needs a trip out (10)
I believe the answer is:
pedestrian
'one without a car' is the definition.
I can't tell whether this defines the answer.
'needs a trip out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'needs'+'a'+'trip'='needsatrip'
'needsatrip' with letters rearranged gives 'PEDESTRIAN'.
Can you help me to learn more?
(Other definitions for pedestrian that I've seen before include "chap on zebra could be?" , "he goes for a walk" , "lame" , "Walker; prosaic" , "Unimaginative" .)
