You've gone from mentioning a behavior that you have observed on a few occasions (cyclists apparently deliberately blocking a road, with help from a car - most likely some sort of race training) to stipulating it as the norm, which is clearly not the case. This is like the false premise of the poster above that '[s]ince bicyclists want to own the lane, they'll ride to the outside.' You're both taking examples of the worst behavior by cyclists and generalizing it to encompass all cyclists.

Incidentally, I don't own a bicycle and haven't for a long time, nor am I any fan of rude or irresponsible cyclists, whose existence I happily acknowledge.

If that's how you interpreted my response, then I apologize; that was not my intent. It was simply an observation directly responding to the post immediately above mine, not intended as a generalization.

The vast majority of cyclists that I've encountered are perfectly fine and do not engage in those behaviors I was referring to. I've simply noticed that often the ones that are loudest and most outspoken about "sharing the road" in these debates are often the ones that seem willing to share the road the least, and that immediately changes the tone from a productive one to one of "us versus them".

Ah, I see. I certainly agree with your observation that the most vociferous cyclists frequently turn out to have the worst road manners.
