Ultimately people just don’t want you to cycle. This is very much a cultural thing. Anyone cycling past age 15 or so is either poor or dangerously counter cultural. One of the most interesting things about the Netherlands is that is very little bike culture! You don’t see people signalling with messenger bags, cycling caps, bike brand stickers etc. because choosing to cycle is not unusual.
As a pedestrian (I am not wearing headphones) please ring your bell if you are passing me on a shared path.
It is very frightening to have a cyclist suddenly appear in your field of vision, from behind, terrifying.
