To be pedantic, pedestrians only have right of way if they have started crossing (per highway code 170)
170
Take extra care at junctions. You should.........
watch out for pedestrians crossing a road into which you are turning. If they have started to cross they have priority, so give way
I hasten to add that of course a reasonable driver would ALWAYS give way, but they are not obliged to and plenty don't even give way when they are meant to!!
