Where Americans can manage without crashing cars (5)
I believe the answer is:
maine
'where americans can manage without crashing cars' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
This is all the clue.
Can you help me to learn more?
(Other definitions for maine that I've seen before include "state of USA" , "American state, capital Augusta" , "somewhere in America" , "North-east American state" , "US state, capital Augusta (5)" .)
