I believe the answer is:

road hog

I'm a little stuck... Click here to teach me more about this clue!

'thoughtless driver' is the definition.
(I've seen this before)

'reportedly took vehicle over corner' is the wordplay.
I cannot really understand how this works, but
'over' could be 'o' (cricket abbreviation) and 'o' is present in the answer.
'corner' could be 'hog' (both can mean to monopolise or dominate) and 'hog' is found within the answer.
The remaining letters 'rad' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?
