I mean the experience of walking along a pavement (or sometimes cycling) on a main road and having to check for motor vehicles coming from behind you at every single crossing because current fashion dictates "no, no, it's better to leave all the side streets open. Closing them and removing all conflict is actually bad".
I mean, maybe you're arguing it's the least bad of the various alternatives, but it's certainly not good.
By which you mean craning your neck 180 degrees every few metres to make sure no one's about to kill you.
I know there are problems in a few places where all of the side streets have been closed creating a nice motorway effect. But keeping all side streets open in the desperate hope it might make motorists pay more attention is letting the drivers win at the expensive of massive amounts of pedestrians and cyclist comfort.
I don't think we know how well continuous pavements might work in this country - there's only a handful of them and on most we've managed to engineer some ambiguity back in.
