I can't believe the amount of people I saw wearing headphones on their bikes this morning. It's really bugging me since I got bumped the other day by a guy who had his headphones on and didn't hear me yell "left" as I went around him.
You're not in a car. You have nothing protecting you if someone decides to run you over. You are putting other cyclists in danger as you listen to Vampire Weekend. Stop pretending you are the only thing on the road. Headphones really just makes you look like an inconsiderate ass.
