I infringed once but in my defence I was PUT and the instructor was RHS. He knows who he is.
All I can say is that I am crap at navigation. I do not fly enough to get much better but I know it so I tend to be well away from anything that looks like trouble. Charts are crowded and can be complex but then they have to be. I always ask what I should look out for even if it makes me look stupid. I don't mind sounding stupid but in the clear. I do mind looking stupid while cutting up a 737.
I was once on a flip which ended with the newish pilot losing his priviledges for a few years. It taught me a lesson which has stayed with me for thirty years.
Too many of us think we know it all, it is the same on the roads.
