Too many close calls with inattentive pedestrians in my area. I ring, no move, or worse, they get startled, and turn around into the middle of the bike lane. If I have to choose between coming off as rude and keeping my brain enclosed, I know what to do.
You need to ring when you are still some way away, so they have time to react, and if they don't you can slow down and ring a second time. And travel at an appropriate speed for the location.
(I have an ebike, so this is especially important. Mine is a legal one: 25 km/h max, 250 W, etc. If yours is faster, this is even more important.)
i like to sing "geeettt outt of the biiiiike laaaannne!" as loud as possible with my big fat tenor voice as i ride past them ringing my bell repeatedly the entire time. a single bell ring never seems to get anyone's attention
