Puts on fresh clothes, as the car driver does (7,4)

'the car driver does' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'puts on fresh clothes' is the wordplay.
I cannot quite understand how this works, but
'clothes' could be 'change' (change is a kind of clothes) and 'change' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

'as' acts as a link.

Can you help me to learn more?
