Yep, an increasing number of riders (mostly younger) have earbuds or earplugs in and seem unable to hear anything quieter than a car, so I take the comment in the opening post about cyclists not calling out before passing with a bucket of salt. Why wouldn't they call to an animal that can kill them by accident? Be serious.
Well I am merely reporting what the riders said to me, you can take it with whatever condiment you prefer but it happened and I suspect it happens elsewhere.
You also contradict yourself in saying that the riders wouldn't be able to hear due to earbuds yet then say why wouldn't they call out?
Think only one who needs to be serious is you.
