Well, just to follow up, I have seen a few cyclists that are flat out in the way. I guess if you pay attention and are comfortable by riding on roads, then I hope it remains problem free. Personally, unless it were a road a lot less traveled, you won't see me riding on it. Other drivers don't pay near enough attention, and I am not going to put my life at risk to avoid bumps on a sidewalk. Again, if this is what you live for, then by all means I will not stop you, but I wish you luck. Stay alive.
