Oh don't get me started.

It's hard enough with nothing in (generic) your ears to hear what's going on with wind and everything else. I don't care how low the volume is. It's a safety issue for everyone involved, not just yourself. I don't appreciate the need to be extra cautious because you want to listen to tunes.

What do I mean?

If I come upon someone with headphones in I am now forced to watch them like a hawk for any sudden motion into MY path. I don't know if the headphones are on, off, blasting or whispering sweet nothings in French into your ears. All I can do for MY safety is watch you and hope to god you hear me coming so you don't cut into my line.

Regardless of the volume, one ear or two, that is inconsiderate to other people on the road because WE DON'T KNOW if you can hear us.

Personally, I'd like to throw a tire pump into the spokes of the people I pass that have headphones on so loud that *I* can hear them. Ahghghghgh!

(We actually had to go into traffic to pass an A$$ that was jogging in the bike lane with headphones on so loud that he couldn't hear us SCREAMING "On you left!". There was a sidewalk too. Instead, he decided to run WITH traffic in the middle of the bike lane with headphone blaring.)

And personally, I don't really care if people need the music for company, comfort, motivation, etc. Those are their own personal issues/needs. It's when they affect MY safety that I get angry.
