Ought listener love plot to protect one from inhuman driver (9)
I believe the answer is:
autopilot
'ought listener love plot to protect one' is the definition.
I can't tell whether this definition defines the answer.
'inhuman driver' is the wordplay.
'inhuman' becomes 'auto' (I am not sure about this - if you are sure you should believe this answer much more).
'driver' becomes 'pilot' (I have seen 'Driver of aircraft' mean 'pilot' so perhaps 'driver' could also mean 'pilot').
'auto'+'pilot'='AUTOPILOT'
'from' is the link.
Can you help me to learn more?
(Other definitions for autopilot that I've seen before include "Robot flier?" , "Device that keeps ships on a steady course" , "George (sl.)" , "flight aid" , "It can fly plane" .)
