I am very careful at 4-way stops - not worried about cars but about the cyclists who do seem to whizzzzz through them!

At a regular 2-way stop, I do what Veronica does, downshift, unclip, come to almost a complete stop, verify there is no traffic (left, right, left) and then proceed through. I try to do what I call a "rolling track stand" and I come to a complete stop, in an easy gear, if I see or HEAR any traffic coming.

At a 4-way, I am less careful unless I see other cars approaching, as I fully expect any cars approaching to come to a complete stop. If there are other cars, I stop and wait my turn.

I also signal at all intersections and really do take seriously my responsibility to obey traffic signs. Now, if I'm out in the middle of nowhere, and have complete view of the intersection I am more likely to go right on through. Its strange, in the same circumstance in a motor vehicle I would stop completely.
