Driving an orange car shows hubris (9)
I believe the answer is:
'hubris' is the definition.
'driving an orange car' is the wordplay.
'orange car' can be anagrammed to 'ARROGANCE'.
But, I'm not sure how this is indicated.
'shows' is the link.
Can you help me to learn more?
(Other definitions for arrogance that I've seen before include "Conceit, self-importance" , "Excessive self-importance" , "Conceitedness" , "Hauteur" , "Overweening self-importance" .)
