Not paying attention in Leeds she crashed (8)
I believe the answer is:
heedless
'not paying attention' is the definition.
(I know this)
'leeds she crashed' is the wordplay.
'crashed' indicates anagramming the letters.
'leeds'+'she'='leedsshe'
'leedsshe' is an anagram of 'HEEDLESS'.
'in' acts as a link.
(Other definitions for heedless that I've seen before include "Without caution" , "Showing a lack of care or attention" , "Reckless, careless" , "Incautious" , "Led Hesse (anag)" .)
