I for one prefer not to use a bell but I do however use my vocal cords frequently. Did you by chance say anything?? I like "heads up" when people I pass are looking downward. (Passing on your left/right isn't always the best alert I have found). I have had to repeat myself once or twice but always had enough time to avoid incident...
And as for the car driver, perhaps they won't recognize you the next time.![]()
