Bandit's crazy road speed (9)
I believe the answer is:
desperado
'bandit's' is the definition.
(I've seen this before)
'crazy road speed' is the wordplay.
'crazy' indicates an anagram.
'road'+'speed'='roadspeed'
'roadspeed' is an anagram of 'DESPERADO'.
(Other definitions for desperado that I've seen before include "Bandit, outlaw" , "Gangster" , "Reckless criminal" , "reckless one" , "Wild ruffian" .)
