I've encountered this, and the bicyclists are unsympathetic to motorists who are stuck driving at 5mph.
They need to share the road as well, not just hog it.
I live in thickly settled Alexandria, Virginia. How is it that bicylcists are allowed the glide right through stop signed intersections, while those of us in cars must stop?
One bicylist on a road is one thing.... some are better than others, but this was an organized special event, where the bicycles should have been granted more leeway and patience by any driver. Good grief people, slow down, go around and relax. There is no right to never have another citizen slow you down on the highway.
My sentiment exactly. Whatever happened to ridding single file when vehicles come along behind, simply to let them go by safely. Cyclists do have an attitude and it has caused accidental deaths as a result. There are many blind hills out where we live in the country with speed limits of 60 mph, so you know what happens when you come up over the hill and the lane ahead of you is suddenly blocked (clogged) with cyclists........THUMP....SQUASH....SPLASH...
