Surely the expectation in London is that pedestrians will step out in front of you. Coming out of a busy London Bridge Station in a morning, you can guarantee a good half dozen will cross in front of me without even a glance.
No sense getting aggravated and honking, bell ringing, and yelling at them, I slow down as necessary. I'm minded that we should all give way to pedestrians, it's our default state. Give them a smile and wave them through, you'll both have a nicer day.
But yes, I'd hope a higher standard of care would be applied to drivers. I suspect, as ever though, that I'll be disappointed.
