For general intersections where I have a stop sign, I refuse to go and wave drivers past, only proceeding when it is clear. If don't have a clear view of all traffic coming from both directions, I assume the drivers don't either. Many people I know have had close calls, and a person interviewed for the campus newspaper was hit in a situation like that.

It happened so often at one intersection that I finally gave up and altered my route.

One thing I like to do at certain MUP crossings is hold back and scan for cars in both directions. If I see cars coming I'll stop far enough back I don't draw their attention. When I think I see a clearing I'll coast forward, check again then proceed across.
