This is always a tough call for me.
On one hand, I've found that I get more room and respect from motorists if I stop at the reds with them. Misery loves company. If I blow them, after checking that it's clear, they tend to pass me closer a few minutes later, as if to say: "If you're exempt from the rules of the road, then I don't have to share the road with you."
If the stop sign or red light is part way down a hill or at the bottom, and I can see it is clear, I'm about 95% likely to blow it.
