Riots most awkward for people in cars (9)

I believe the answer is:

motorists

'people in cars' is the definition.
(motorist means a driver)

'riots most awkward' is the wordplay.
'awkward' is an anagram indicator.
'riots'+'most'='riotsmost'
'riotsmost' with letters rearranged gives 'MOTORISTS'.

'for' acts as a link.

(Another definition for motorists that I've seen is " road-users".)

I've seen this clue in The Times.
