Crossword Genius

Driver that goes with the flow (5,5)

Ross

I believe the answer is:

water wheel

'driver that goes with the flow' is the definition.
(wheel driven by flowing water)

This is all the clue.

(Another definition for water wheel that I've seen is " turbine".)

I've seen this clue in The Telegraph.
