It's funny to me how this devolved into the old cars versus road bikes issue. The issue at hand was a pedestrian trying to cross the road who was rudely shouted at to move as they had the right of way. That is incorrect and if it's the same group I encountered the other day in the Wheel House area then they should be smacked.
There seems to be a "leader" who constantly stays out in traffic riding more than one abreast. This is not only illegal, but unsafe. I don't care how much your bike costs, you've trained, or you think you have some sort of right; if you can't obey the simple basics of safe bicycling on a ROAD then you don't deserve any respect.
Respect those around you and be amazed at the return.
