Some areas short of a means of transport (3)

Ross

I believe the answer is:

ass

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

'a means of transport' is the definition.
I can't tell whether this defines the answer.

'some areas short of' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'ASS' is hidden in the letters of 'areas short of'.

Can you help me to learn more?

(Other definitions for ass that I've seen before include "sap" , "Idiotic animal" , "mug" , "Jennet" , "Foolish person; animal" .)

I've seen this clue in The Globe and Mail.
