It's not just bikes.... Cars in the left lane... CLUELESS! Get over to the right ASSHAT!
I do like it when I'm in Texas, OK, ect.... Rolling along on a country 2 lane road and you come up on a slower moving vehicle and they actually maintain their speed, But pull over to the shoulder and allow you to pass. Or when they are making a left hand turn they signal "left" then merge into the oncoming lane to make their left turn into a driveway or whatever allowing you to go past them without slowing down.
There are some courteous drivers out there.
