Personally, I'd rather focus on other traffic and the ride's situational awareness, rather than on whether I turned off the turn signal. I've used it since 1975.
My, Cb700SC doesn't have a turn buzzer and the indicator is not in field of view. Doesn't self cancel, either. And yes, I leave that thing on frequently.
I also find irony in those who are annoyed by a buzzing reminder to do the right thing for others, but still think loud exhaust is just wonderful for ALL to hear.
Cheers,
These are pics from my 78 CB550.
