Avoid bumper car? Not quite (5)
I believe the answer is:
Here is my best explanation:
'avoid' is the definition.
(dodging is a kind of avoiding)
'bumper car? not quite' is the subsidiary indication.
'bumper car?' becomes 'dodgem' ('Dodgem' can be a synonym of 'bumper car').
'not quite' means to remove the last letter.
'dodgem' with its last letter taken away is 'dodge'.
(Other definitions for dodge that I've seen before include "Duck, move to avoid", "shady scheme", "Avoid - old American car", "duck", "Avoid by a quick move", "Avoid by quick movement", "Wild West city", "evasion", "Sidestep with trick?" and "Evade - trick".)
