Fair play for car drivers (7)
I believe the answer is:
dodgems
'fair play for car drivers' is the definition.
I can't judge whether this defines the answer.
'car drivers' is the wordplay.
'car' becomes 'dodgem' (I've seen this before).
'drivers' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'dodgem'+'s'='DODGEMS'
Can you help me to learn more?
(Other definitions for dodgems that I've seen before include "fair features" , "fair source of revenue" , "Fairground attraction" , "Fairground cars" .)
