Handy, you are misreading what I thought I wrote:
"I would have spotted the pedestrian in the first place and moderated my speed"
Rather than
"driving along staring at the speedo confident that 30 mph must be safe..."
This doesn't mean that
I am confident, it means that the "stick to the speed limit and you will be safe" message is making
others confident (incorrectly so).
Your suggested poor road design is exactly a scenario where my speed would have been moderated down such that I can stop in what I can see to be clear - sticking to the 30 limit is just wrong in that situation, but is what the official message suggests is correct. My COAST style driving means that in most cases I would have anticipated the possibility of them running out of an entry, but there is, I admit, the possibility that they would have run out so fast and so late, that despite the extra space that I would have allowed for the blind entry, they have dived in front of me. Well then, I am sorry but it qualifies for a Darwin award - such a person is just as likely to have run into a baby pushchair and knocked it flying into the road in front of an oncoming bus - perhaps they deserve a little criticism too?
You cannot drive to cover the most unlikely situations, just the possible ones.
I wouldn't have such a sticker because to me it implies support for the camera scheme - if it had instead been crossed through like this, then it gives a totally different message:
