Woman left behind by inconsiderate driver? (4,5)

'inconsiderate driver?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?

'woman left behind by' is the wordplay.
'woman left' becomes 'widow' (woman whose husband has died).
'behind' says to put letters next to each other.
'by' becomes 'golf' (I can't explain this - if you can you should believe this answer much more).
'widow' put after 'golf' is 'GOLF WIDOW'.
