This also raises another issue.
Quite often I am flying on a combination of GPS and pilotage and know exactly where I am and am tracking to avoid airspace by a small margin. Two examples spring to mind; the SW corner of the LHR zone which is conveniently marked by Bagshot mast, and D011 which has a TV mast a mile South.
It is then difficult to know how to react to a statement such as "turn 20deg left to avoid....". I don't like to say "I know what I am doing, ta very much" because I know that the controller is trying to be helpful, and it's nice to know that (s)he is looking out for me, equally, I don't really want to turn 20deg when I am quite confident in my track.
Suggestions/recommendations, please?
