Thank's Tara for your help.

I would answer it, but it's expired. Tara made a general point and although it's not wrong, it's not the full answer. Å drive can also mean to run as in "I run a shop", "Jeg driver en butikk"

I believe the difference is this... but perhaps a native Norwegian can verify... Hva driver du med? - What do you do? Most specifically, I think it's more like "What do you do for a living?" e.g. job Hva vil du gjøre? - What do you want to do? or What will you do?
