Pedestrians wearing ear phones are very annoying to bicyclists.

It happens all the time. You're out for a bicycle ride, there's a pedestrian ahead, you ring your bell or sound your horn, the pedestrian just keeps in a straight line and doesn't move to the side. You sound the bell or horn again. No reaction. Then as you pass the pedestrian, you see the ear phones sticking out of his or her ears, and then you get annoyed as that person could even comfortably work on the flight deck of an aircraft carrier wearing those ear phones and never be able to hear the roar of military jets taking off, those ear phones block out external sound that well.

People, you like wearing ear phones while out walking, go do it in New York City, where bicycles are totally illegal, on both street and sidewalk. In New York City, operating a bicycle within the city limits, including on the street, carries up to 5 years on Rikers Island. And in New York City, all lanes with the bike symbol are in fact motorcycle lanes, built for motorcycles.
