since I rarely ever ride in group rides, and am usually riding solo I rarely call out unless it is to say hi to someone if I come up behind them, or is I am on a bike path and there are walkers sho are taking up the whole path.

I do however object to the hammerhead trains that whip by me close enough to blow my eyeglasses off without so much as a " hi there", or a polite ding a ling and would almost welcome a rude shout to being blown off the path by the speed train.

I dislike autos who lean on the horn, but don't mind a polite little two tap which says hi to me, or perhaps " I am a fellow rider."
