IO540: "Most NOTAMs are a load of crap"
Now then, I do agree that most NOTAMs are a complete pain in the ar*e to unearth, read and inwardly digest but God help you if you miss that really important one that you didn't expect.
The Dutch pilot who found himself in the middle of the Red Arrows at Eastbourne springs to mind.
You are supposed to be in command of your flight after all.
By the way, having spent my first 18 years flying for Mrs Windsor, I can think of thousands of occasions when "not flying in accordance with the Rules of the Air" would have applied but such occasions were usually covered by NOTAM.
