If there was poor visibility for the driver, there's almost certainly poor visibility for the pedestrian too. Most are sensible enough to walk a little further to where they can get a bit better look at what traffic is coming.

If I did hit someone at a visibility blind spot I'd expect to be shouted at by the cop too for not slowing down to a speed suitable for the visibility, and that the speed limit is a maximum sir. In that special sarcastic voice, common to all British cops. That might be later reflected in my fine or penalty. :)

Hah, fair enough!

For some reason I'm imagining the worst-case scenario of a pedestrian completely oblivious to what's going on around them and just crossing without looking on a busy street, which I realize is pretty unlikely.

Yeah, that's not how it goes. If it does go that way (some people for example might have mental issues and go into the street, or be disoriented etc), it's not usually held up to the driver if they are hit, except if it's shown that they could have realistically prevented it.

Then you need to go slower than hhe limit.

At least in my country, there are two forbidden concepts in traffic law of "excessive speed": one is driving over the defined limit, another is driving at an inadequate speed for the conditions. If you get into an accident because you couldn't stop, but could have if you had been going slower, you're guilty of the latter (that's the gist, exceptions apply).

The speed limit is called a limit for a reason. If prevailing conditions make it unsafe to drive at this speed then you're supposed to slow down.

Basic Rule Of Speed: Only go so fast you can stop within visible distance. If there is not enough room for oncoming traffic, make it half the visible distance.

Well, the city should light them properly and clean them up then?

From my original post:
