I know this topic has come up before, but I'm bringing it up again. What's your opinion on it?

Right now I'm rather peeved at someone who always shows up to our group rides with ear buds on. He does the yo-yo thing where he pedals real hard to catch up, brakes(!), and then coasts. I got stuck behind him and had to swerve off the road to avoid crashing.

Then, last night, after doing his pull, he almost got blasted by a truck when he dropped back. Not only did he not look to see if cars were coming, but he swerved out into the middle of the road instead of inching over a foot or two!!!! He probably could have heard the truck coming (it was a diesel) if he didn't have headphones on. I've never been so freaked out on a ride before.

Do you guys think its appropriate to wear headphones when riding in a group? I feel like he is endangering the rest of us by not being as alert as he could be.
