I will admit I do if no one is around. If cars are present, I stop. I'm talking about rural riding here, not city riding.
I know that is not the right thing to do. But if a car is present I stop so as not to make them mad and that includes cars going the same direction as me. No need to "push someone's buttons".
Sometimes I think we are guilty of making people mad and that is dangerous to all of us.
I never run a stop light. Ever. Then again I don't ride where there are stop lights
I never run one in the car, unlike people driving thru my neighborhood.
