Potentially feature mistakes of learner overwhelmed by street hazards (4,5)

'potentially feature mistakes' is the definition.
I know nothing about this answer so I can't judge whether this works.

'learner overwhelmed by street hazards' is the wordplay.
I cannot quite see how this works, but
'learner' could be 'l' (as in a learner driver with L-plates on their car) and 'l' is found within the answer.
'hazards' could be 'potholes' and 'potholes' is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...

'of' acts as a link.

Can you help me to learn more?
