On these, there's a fair chance of bumping into people (7)
I believe the answer is:
dodgems
'people' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how they can define each other.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for dodgems that I've seen before include "Fairground cars" , "fair features" , "fair source of revenue" , "Fairground attraction" .)
