There's only a few types of car that will be "aware" of cyclists and I don't think ringing a bell will help their algorithms. Getting the attention of a driver, meanwhile, is difficult with a bell as often they'll be in a semi-soundproof cage with loud music on. (Also deaf drivers are a thing).

I've never really considered using a bell for motorised traffic. I did once buy a loud air-horn, but it was so loud and abrasive that I never used it as it seemed really rude.

It works surprisingly well if the car isn't moving quickly. Cars aren't as sound isolating as you'd think. My main use-case is that a car is stopped at an intersection, or crossing my lane so they can turn, and I'm worried they'll pull out and hit me because they're looking the wrong way focused on car traffic, and in these situations they almost always hear my bell.
