I find it amazing how many pedestrians you pass wearing ear buds, and you know they can't hear your bell and you know they will get startled when you zip past.
There is a local canal tow path/walkway near me called Lee Valley Way, which I like to use on the odd weekend.
It is quite popular with people who like to fish, they like to walk along side by side having a little chat carrying all their fishing gear (which is what you would be expecting on a nice lazy Sat or Sun).
I enjoy playing a little game with them, by riding as quietly and closely as I can to see how long before they notice me, I find it rather amusing

, as they all apologise quite profusely depsite the fact I am no rush to get by them (it's a shared space for recreation, so I am in no rush, and I believe everyone should be free to use it without concern).
London is a pain for pedestrians just stepping out without looking, some with earbuds and some without, although those staring at mobile screens tend to irritate most, or stepping out in front of or between buses is another favourite...
I had to shout very loudly at a chap "bike coming" this morning, he obviously wasn't going to look, this depsite the fact he was going to have to step down off the pavement and into a dedicated cycle lane to get across to a bus island (bikes have priority, but I could see what he was going to do so had slowed down a little)...
Thankfully it has been only twice where I have been nearly wiped out by a pedestrian stepping out between a van/lorry and going across the cycle lane I was in, no lifesaving check from them, just walked into the cycle lane... (both taking me very close to colliding with vans/cars and almost taking off wing mirrors in having to take such last minute avoiding actions).
