I frequently walk my dogs without leash. They follow my command, don't disturb other people or dogs unless both parties engage and generally I don't do anything that someone who has a leash wouldn't be doing. They also walk side-by-side with me when off-leash. This is very common in the city I live and surrounding area (Barcelona, Spain and Catalunya).

I'm not afraid they are gonna attack me, although sometimes humans do attack other humans, most of them are fine so no need to worry in general.
> but where I’m from we have a scourge of ignorant owners who are not in control of their dogs. They ruin it for everybody.
Yes, I agree, it's terrible when owners have no control over their dogs. But that's not relevant to the leash itself, that's relevant to the expertise of the owner. Dogs on leashes misbehave as well, and can easily (if wanted and the owner is a terrible one) unleash themselves by either raw power or the owner not paying attention.
