Perhaps, when you're no longer 'an inexperienced pilot' you will understand; perhaps not. But at least you're less likely to say things like "anybody who wilfully breaks the letter or spirit of (Rule 5) is, in my book, verging on recklessness."
On the other hand, if you mean 'reckless' as in recklessly ignoring the risk that some busybody might report them to the CAA, then I agree with you.
As you say, of all the people who posted, only two or three thought the M40 pilot was flying dangerously. Doesn't that tell you anything?
