WOW! That guy sounds like a knob who is going to get himself killed. He gives good cyclists a bad name.

Yea, this past weekend riding... I was horrified to see a guy dart over a lane to the left to pass people... and a car was coming from behind. He didn't even look. I yelled at him... but I doubt he heard me.

I also get really annoyed in my groups when we yell "car back" and no one moves over (when we are on a 1 lane road). It's just rude, and makes me understand why cars want to make us road kill.
