So.....let me get this straight.....you're bitching because you want to use your own car, and you want the RAF to give you money to do so, for personal convenience. Your start and finish location for things such as duty journeys is your duty station, not your front door.
Suggest you try the pragmatic approach and give your MT WO a call and pop over for 5 min, explain the situation and see if someone with about 30 yrs experience of MT and regulations can't find a good answer.
Note to above: Best tried in a non-confrontational style
