Right lane to turn one of us to strangers (9)
I believe the answer is:
earthling
'one of us to strangers' is the definition.
(term for a human from an alien's perspective)
'right lane to turn' is the wordplay.
'to turn' indicates anagramming the letters.
'right'+'lane'='rightlane'
'rightlane' is an anagram of 'EARTHLING'.
(Other definitions for earthling that I've seen before include "sci-fi character" , "Human being (sci-fi)" , "man so to be called from space?" , "Man of the world" .)
