Unconscious in car (9)
I believe the answer is:
automatic
This clue could be a double definition.
'unconscious' is the first definition.
(thesaurus)
'car' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'in' is the link.
Can you help me to learn more?
(Other definitions for automatic that I've seen before include "Reflex" , "Like George" , "Type of gun or car" , "Involuntary or mechanical" , "washing-machine?" .)
