Why is the cyclist "too close" (your words) and what's this nonsense of designated spaces? Pedestrians can walk where they want in most shared spaces; they are only cowed into using the pavement because of fear of the motors.
UK car culture once again clouds the mind of a cyclist.
Well I'm imagining it happening on the road I'm looking at as I type, which has a pavement either side of a four lane road. The pavement is for pedestrians only. The road has two lanes either way. At the moment one each way is reserved for buses, taxis and cyclists, and one each way is for any type of vehicle.
Vehicles cannot use the pavement. Pedestrians can cross the road, but vehicles have priority on it - at least where I am looking, there is a crossing a hundred yards or so in either direction but I can't see either. I think this is a pretty average road set up? Pavements for pedestrians flanking a road where pedestrians can cross but vehicles have priority?
Of course a pedestrian cannot expect to just walk across the road without paying attention. And of course it is possible to step on to the road in such a way as it is inevitable that a vehicle will hit you if you do so too close. One would hope that the rider/driver would see you and stop, but that isn't always possible. For example there is a post box and advertising board by the side of the road that I can see. If a pedestrian were to emerge from behind that onto what is currently the bus/taxi/cycle lane as a cyclist were passing I doubt a cyclist could stop in time - especially as there is a junction slightly further ahead (and the crossing mentioned) which the cyclist might be looking at briefly. Besides which I've had people cross in front of me when cycling and had to lock on to avoid them twice since I got back on a bike a few months ago - pedestrians don't see bikes as much as motorists don't.
I don't suggest that it is often the fault of the pedestrian, just that it is possible.
