Good topic. as a cyclist, I encourage cyclists to be more polite in these group settings. It is not safe as cyclists to ride in large groups blocking traffic when the option of not doing so is possible. I know for fact that some groups of cyclists feel an overwhelming right to take up the lane and will refuse to move or even make it difficult to pass. this is rude and unacceptable in my opinion as both bike commuter and occasional car driver. It only gives cyclists a worse name to dedicated motorists. be safe and courteous, the same as you expect cars to behave.

we are all on the same team at the end of the day, just trying to get wherever it is we are going.
