Local field; nothing going on except your flight; land it.
Solve the crap later. By definition you're perhaps wrong, but that Cessna 152 you could land as well without clearance on some strips, no?
Its only to cover your ass in case something might go wrong.
If you're sure the runway is yours, why don't take it?
You'd even have the backup of the local green party..
LHR? would't try it..
CDG? you would have gotten the clearance already while being number 3 on 9 miles final.. what's the difference in this case?
