Faith in inexperienced driver one follows, in part (8)
I believe the answer is:
religion
'faith' is the definition.
('religion' can be a synonym of 'faith')
'inexperienced driver one follows in part' is the wordplay.
'inexperienced driver' becomes 'l' (I've seen this in other clues).
'one' becomes 'i' (Roman numeral).
'follows' is a charade indicator (letters next to each other).
'in' is an insertion indicator.
'part' becomes 'region' (region is a kind of part**).
'l'+'i'='li'
'li' put into 'region' is 'RELIGION'.
'in' is the link.
(Other definitions for religion that I've seen before include "Particular system of belief" , "System of belief or worship" , "Organised system of faith" , "Belief in and worship of god or gods" , "Institution for worship" .)
