Start to drive car with Tito: nasty tyrant (8)
I believe the answer is:
dictator
'tyrant' is the definition.
(I've seen this before)
'start to drive car with tito nasty' is the wordplay.
'start to' says to take the initial letters.
'with' is a charade indicator (letters next to each other).
'nasty' indicates anagramming the letters (a nasty or wrong spelling).
The initial letter of 'drive' is 'd'.
'car' after 'tito' is 'titocar'.
'titocar' is an anagram of 'ictator'.
'd'+'ictator'='DICTATOR'
(Other definitions for dictator that I've seen before include "Tyrant like Mussolini or Franco" , "Arbitrary ruler" , "One ordering" , "Chaplin film showed a great one" , "person in charge? Absolutely!" .)
