Drive time around noon — can't wait! (6)

I believe the answer is:

urgent

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

'can't wait' is the definition.
I can't tell whether this defines the answer.

'drive time around noon' is the wordplay.
'drive' becomes 'urge' (I've seen this before).
'time' becomes 't' (abbreviation).
'around' is an insertion indicator.
'noon' becomes 'n'.
'urge'+'t'='urget'
'urget' placed around 'n' is 'URGENT'.

Can you help me to learn more?

(Other definitions for urgent that I've seen before include "Requiring immediate attention" , "To be done asap" , "Requiring early action" , "Extremely pressing" , "Pressing, imperative" .)

I've seen this clue in The Guardian.
